tl;dr ... or watch...
The stores are so similar that most customers don't care which one they go to, and they may even prefer a familiar area (or route) to a slightly closer location.
If a customer needs to go to "the drug store" and they locations are the same, both stores have a shot at that customer.
If a customer needs to go to "the drug store" and the locations are separate, then the customer may choose the other store initially and never see your store. If this ever gets out of balance, it may not get back into balance without external effects such as the other shops around, and large population changes.
Actually, the idea that art and craft are separate is a relatively new, and primarily western, concept. There is an interesting TT on the subject. http://ed.ted.com/lessons/is-there-a-difference-between-art-and-craft-laura-morelli#review

It's a small distinction, but it exists. Scientific language isn't compelled so strongly by popular usage. Linguists probably don't care about it. Ask a biologist. O WAIT
What it actually says because I did all this hard work of clicking on the title:
>Russian mathematician Andrey Kolmogorov furthered our mathematical understanding of turbulence when he proposed that energy in a turbulent fluid at length R varies in proportion to the five-thirds power of R.
>They discovered that there is a distinct pattern of turbulent fluid structures close to Kolmogorov’s equation hidden in many of Van Gogh’s paintings.
>The researchers digitized the paintings, and measured how brightness varies between any two pixels. From the curves measured for pixel separations, they concluded that paintings from Van Gogh’s period of psychotic agitation behave remarkably similar to fluid turbulence. His self-portrait with a pipe, from a calmer period in Van Gogh’s life, showed no sign of this correspondence. And neither did other artists’ work that seemed equally turbulent at first glance, like Munch’s ‘The Scream.”
The ed ted talk.
Personally, I suspect Van Gogh just thought it made for a pretty picture and it's a coincidence that a model could be found that matched it mathematically.
The problem I have with this is that if you take that argument to it's logical conclusion, no-one would ever be able to be creative about anything that's not within their 5km radius. Which means that no-one is going to be exposed to anything that isn't from their circle.
When Madonna used the Japanese Kimono, I became interested in the history and culture of the geisha and learned a lot (and eventually moved to Japan).
It would be a pretty boring world if we didn't use things from other cultures. Are you going to stop using arabic numbers (which came from Hindi language)? Are you going to stop using the English language because it borrows from almost every other language out there? Remember language is one of the most important parts of cultural identity. Ask any Japanese person about their language - language is culture.
I think it's pretty accurate.
Basketball players may be supremely talented, but their height pretty much guarantees they will rarely match the speed (or strength, due to muscle density of longer limbs) of American Football's best.
Obviously, there are freaks like Karl Malone, but that's the exception, not the rule. Same goes for Baseball.
Whereas you can almost guarantee every player at Wide Receiver, Cornerback, Linebacker, Safety, Running Back are physical specimens likely among the nations elite.
Also, for hilarities sake, here's a <em>normal</em> person compared to NFL players, one of whom (Ford) ran a 4.28s 40yd dash.
> In theory it keeps vulnerable people directly out of harm's way, but vaxxed people can still go to store with covid, spread it, catch it, take it from there and go grocery shopping or to their friends and spread it to non vaxxed.
Yes they can..... at a rate of about 1/10th of what unvaxxed people will do.
We're talking about a 90% drop in transmission right there. Add in masks and handwashing? That drops it even further.
It's theory, in the same way that we have a "Theory of Relativity". It's pretty much fucking reality. (http://ed.ted.com/lessons/what-s-the-difference-between-a-scientific-law-and-theory-matt-anticole)
Actually, for my college speech class, I am doing a presentation of sugar addiction and how consumption of processed sugar negatively affects your memory. Recently, in Australia a university started to treat sugar addiction with the same methods one uses for other drugs. Here is an interested TED talk on the subject of sugar addiction and this is the article I am basing my presentation on. This is the study on how sugar messes with your memory.
In Old English there were lots of ways to indicate plurals. A few of these have survived. The plural for "man" is "men," the plural for "goose" is "geese."
But the plural for "door" was "doora" and the plural for "ox" was "oxen." Just about everything had it's own special case for how to make it plural.
"S" was used for some words.
When the Vikings came to England in the 800's many of them stayed, and they married the English but they spoke Norse, not English, so all of these complex rules for English plurals were annoying.
The language hybridized some, and the Vikings just said "To heck with it, I'm not going to bother learning all of this nonsense," and they simplified the language when they spoke it. The "s" method was easy to understand, so it crowded out the traditional way. It caught on eventually, even with the native English speakers because it was simpler.
A few exceptions survived as historical oddities. That's why the plural for "child" is "children," and "tooth" is 'teeth," but most of them went away so we have "books" instead of "beek."

I think one of the most discouraging things is that many, many girls are raised thinking that you're only acceptable if you're perfect. Later in life they're far less likely to try things b/c they're so worried they're going to be bad at it // fail.
Doesn't mesh well w/ engineering, which says "you don't know shit until you've completely fucked it up at least three times, repaired it, accidentally stepped on it, and finally rebuilt it from scratch!" Moreover, we're not given much room to fail in school-- that's why everyone wants us to have work experience, after all-- so leaving the formulaic-environment of school is probably a total "culture" shock. Perfect no longer exists; hell "problem statements" don't even exist, let alone "solutions" to grade oneself against. That's all very scary if the pillar of your confidence comes from grades and being able to do everything correct on the first attempt.

...a couple articles on the topic:

False positives are fairly common and that is why further testing is done to confirm. I dont know what the protocol is in WI but in the UK dogs are evaluated every 6 months.
Depending how the dog is trained. Some are trained speficially to locate human blood (from just bled to months/years old). They are taught to discriminate the individual scent of blood and indicate on that.
Cadaver dogs are usually trained on a combination of smells. Decomposing flesh, bone, blood etc.
Dogs are able to discriminate scent even in fires. In fact in arson detection the dog is a very valuable tool to find areas that indicate an accelerant has been used.
The best way to explain this is, if you walk into a home and smell coffee and bread baking. The dog smells the breath, urine, skin scents of the person. The yeast, the flour, the salt. The coffee, the milk, the sugar.
They can smell the past and present http://ed.ted.com/lessons/how-do-dogs-see-with-their-noses-alexandra-horowitz
False positives occur most often from accidental cueing by the handler. This is a little less likely in this case as it seems they had not yet zoned in on the area they believed was the crime scene.
Sometimes, against a uniform, bright background such as a clear sky or a blank computer screen, you might see things floating across your field of vision. These "floaters" are not any kind of external objects, nor are they alive. Rather, floaters are tiny objects that exist inside the eyeball, and cast shadows on the retina - the light-sensitive tissue at the back of your eye.
If you'd like to learn more about floaters, watch the TED-Ed Lesson What are those floaty things in your eye? - Michael Mauser.

Hello, im a PhD student and im teaching at the moment to science students in a London university. I've realised that the younger they are the easier they relate to simple ways to explain some basics and then built on more abstract ideas to sort of cement your logic. This basically explains to them that trivial things are not so trivial.
A nice video I just saw is: http://ed.ted.com/lessons/rethinking-thinking-trevor-maber
A suggestion would be you could built a lecture around this and somehow link it to literature and art? Maybe argue that literature is a minds way to accept possible scenaria of situations that happened and value the books outcome thus embedding deep lessons linked to family and old memories and change ideals in society, eg deep concepts such as Marxism and various ideals you can find even in childhood folklore of various people.
Many parents worry about their kids having to grapple with two languages at once/learning two languages. However, learning two at once is actually better for the child. Not sure how much language is entering into your decision making, but thought it would be something to consider.

It's the Hotelling Model of Spatial Competition according to this video: http://ed.ted.com/lessons/why-do-competitors-open-their-stores-next-to-one-another-jac-de-haan. This video is also interesting becuase it explains a Nash Equilibrium, which has sadly been in the news recently.
It is BS. Here is a TED talk on the subject and also a nice informative page here put up by the national science foundation debunking this common misconception.
I'm pretty sure this misinformation was spread by accidentally cutting of the end of the sentence "you typically only use 10% of your brain at a time" but don't quote me on that.
A web site that is supposed to help you relax but instead makes you frustrated, distracted, and anxious. That hit irony dead on.

You're good. Now breath and relax. And try not to focus on how frustrating it is that I pasted a big ugly URL instead of using Reddit's syntax for links.
> Edit: Actually using -s to pluralize words is from French. German pluralization is much different.
It didn't, though. -s was already used in Old English. When the vikings took over, it became used more. Here's a talk about it by McWhorter. Basically, it's just a different paradigm from Old English survived, and it wasn't because of (Old) (Norman) French.

And the vocab is only in the more advanced words. The most common words are all Germanic.

You are correct, I am sorry.
To make it up, here is a TED talk about how to tie your shoes, and here is a TED talk about how you can totally buy clothes at thrift stores, AMAZING! Or how about that Positive Emotions Open Our Mind!!!
Seriously, it's lots of pseudointelectual bullcrap that is made to sound smart and enlightening and make you feel good about yourself, as if you are learning and becoming a better person. In reality, it's just entertainment. It makes you feel great, but it has little to no content. If you want to actually learn, try watching some actual lectures online. At this point even world renowned universities like MIT are putting lectures for free online.

They do all like commercial locations, however that isn't the reason they open up right next-door to each other. Hotelling's model of spatial competition is the reason why they do it.

I believe it is because it is a dipole, the molecule is an angle (I want to say 144 degrees?) with oxygen in the centre and the 2 hydrogen atoms at either end. Due to how the electrons are shared between the 3 atoms, the oxygen has a slight permanent charge and the hydrogen atoms have the opposite charge - this leads to the whole molecule having one charge at one side and the opposite charge at the other.
With this overall imbalance in charge, 2 water molecules in a liquid state will tend to spin until the opposite charges on each molecule face each other and then be attracted so that they pull closer together (on average) than you'd otherwise expect. Think of a bunch of weak magnets chucked on a tray and shaken around really vigorously (hot water) and then gently (colder water)
With ice, the molecules stop spinning and bumping and stick together. They don't form the most compact structure when they settle down, though, they form the most stable structure, with nice regular sticking points. Think of it like a wild night at a club, everyone dances close, grinding and sweating, swapping dancing partners and generally getting hot, versus bedtime with a partner where things have cooled off a little bit, where sleeping on separate sides of the bed is more stable.

Good suggestion. We just launched something called TED-Ed Clubs which is designed for public schools. The idea is to encourage kids to get to the point where they can give their own TED Talk. You could argue Presentation Literacy will be key skill for 21st century. More on TED-Ed Clubs here: http://ed.ted.com/clubs

Well... the reason is that the most common nouns around the time of the viking invasions of Britain were easy enough to learn, so they kept their old and weird plurals. But the rest were 'dumb' and difficult to remember, so the vikings introduced a simple way of pluralising a base noun. Hence, the modern S.
The age of the word has very little to do with it. Yeah, more recent words will have the plural s applied, but so will plenty of older ones. Most of them, in fact. The key is how common these nouns were back in the day. Geese, sheep, mice, children... these were rather common things to talk about in ye olde viking times, and they remained that way for a long time. So, they maintained their old and weird plurals.
John McWhorter did a nice little lesson on it for TED-Ed. Generally recommend anything by McWhorter, this one is certainly includedin that.
>To even be on pointe you have to have a certain level of ballet training and ankle strength.
Yes, on pointe it's very difficult, which I mentioned. The original video isn't of someone on pointe though and regular fouettes aren't something you only learn if you're in some way exceptional as a dancer.
>Fouettés are not a basic step that all dancers can do.
They are. Like how low a bar are you setting here because that's only true if you include people who took a casual dance class for a few years and ignore the literally millions of people who were a bit more involved and can do fouettes.
>Edit: the seven year old is a student in the Russian ballet school.
>Edit 2: here's a TED talks on the "physics of the hardest move in ballet" http://ed.ted.com/lessons/the-physics-of-the-hardest-move-in-ballet-arleen-sugano
Specifically this is a reference to one of the parts from Swan Lake where 32 are required in a row, on pointe. It's not a claim that a fouette is the hardest dance move in ballet. Though frankly even if one were making that argument it wouldn't be saying much as no single movement in ballet requires you to be an expert dancer in order to do it decently, you can't break ballet down that granularly.
There is a TedTalks that I watched a year ago that changed by wourld
ETA: PLEASE everyone on this thread watch this video. It is amazing. I want to tell every other commented to see it
Wow! There's a lot to go on here!
Since you've not actually asked a question, I'll comment on the human eye in general. If you were asking about the genetics about this or anything else then shout!
You may know that in the eye we have 2 types of cells that detect light - rods and cones.
Rods work best in low light, but only see in one colour. Which is why you mainly see in gray scale in very low light conditions.
When there is more light the cones predominate. Most of us have 3 different types of cone, each of which is better at detecting light at different wavelengths (that is to say different colours). These range across all the colours that we know (clearly if you think about it!) Each type of cone will get a different amount of stimulus from a particular colour, and the brain puts these together to work out what colour the thing is.
Research has shown that some people (women mainly and only a few percent) have an extra type of cone which could perhaps give them the ability to further tell colours apart, or even see colours outside of our normal range - this could even be the unseen (for most of us) infrared and ultraviolet.
This is not unknown in the mammalian world - there is strong evidence that reindeer see into the UV range. It certainly happens a lot in other, more distantly related, species like insects.
This is a good primer into colour vision although not quite what you are asking!

It's not a reason to fear it. It would be a great closing summation. Basically telling the audience that, hey, put what your passionate about into your world. Take you interests and create mysteries, histories, and plot points around what Sets YOU personally on fire. Center the world building around what the writer is enthusiastic about.
It isn't a talk about writing, or how to write. It's a talk about how to world build. So focus on that. This is the best comment about world building I've read here.

Here's a tedtalk about world building. It's focused mostly on fantasy and scifi, but the questions it lists at the end are more or less universal regardless of genre. It's only 5 minutes, so take a gander, see if it helps.
As Oliver sAcks alludes, there are non-fiction examples of memory loss that drive our understanding of how memory works.

Physical attraction is listed as the number one quality in most, if not all, peer reviewed studies on attraction followed by the mental (personality, confidence, ect...).

The majority of human awareness is unconscious (like upwards of 90%). That puts a whole new meaning on the importance of first impressions!
http://ed.ted.com/lessons/why-are-some-people-left-handed-daniel-m-abrams
TL;DW Left handed people have a competitive advantage when the majority of humans are right handed, resulting in a higher proportion of left-handed people. Right handed people have a cooperative advantage due to tool sharing (tools made for the right-handed majority), resulting in a higher proportion of right-handed people. The balance of these two hypotheses gives us the distribution f left-handed to right-handed people seen today.

Today, manufacturers make their manuals available on line in PDF form so consumers can easily get replacements. In the future, the .stl files for replacement parts will also be on line.

>Making the brain 100% usable!
I actually just caught a 5 minute TED-ED video on this a few weeks ago. Animated & worth the watch, but...
TL;DR... the "only 10%" thing means just at any given moment as opposed to indicating that there's a big chunk of our brains that perpetually sit idle. Take away, i guess, is that the brain consumes so much energy that it cant power on all at once.
I have a BS in Biology and I am currently drafting some "superhero" stories as well.
One weekend I googled around for funsies and found these quite entertaining, though they mostly just scratch the surface:
TedEd talks about what if super powers were real
There's even one there that addresses your exact example.
I'd also be happy to help you with any Biology related things, just PM me.
Looks great, I like the nice clean layout though you'll need a way to search it easily when the database is larger. Have you checked out the TED Ed page, it may be of interest to you?
I would have to disagree that this meets the WHO definition. The quote you provided states altering of DNA in a way that could not occur naturally, hybridizing plants (especially of the same species, as your op quote mentions) can occur naturally, it's just that we are facilitating it happening faster. This method of genetic manipulation has been occurring since the first farmers existed. They say the GMO method is often called recombinant DNA technology. This is a test tube method where they introduce specifically constructed chemicals/enzymes to cleave DNA sequences and then add a specific DNA sequence to insert itself and manifest as a desired trait.
According to that same WHO FAQ: >Whenever novel varieties of organisms for food use are developed using the traditional breeding methods that had existed before the introduction of gene technology, some of the characteristics of organisms may be altered, either in a positive or a negative way. National food authorities may be called upon to examine the safety of such conventional foods obtained from novel varieties of organisms, but this is not always the case. In contrast, most national authorities consider that specific assessments are necessary for GM foods.
Implying that GM foods and foods genetically altered using conventional methods should not be defined together.
I just found this short video on cross breeding to create new types of fruit (with apples instead of grapes). It's more of an eli5 but I think it's pretty interesting still and explains well how fruits like these cotton candy grapes are created.

And that is frustrating.
Extreme emotion makes people feel like they are losing control, and losing control lessen chances of survival. While we don't really have to worry about that anymore, our body thinks we do. Tears are used to stabilize your mood. Scientists aren't sure why. It's either a social thing where we cry to signal distress to others or to show submission, or it could be because emotional tears have higher levels of stress hormones directly leading to us calming down.

I'm doing my master's in computing. I took ODE, PDE, 2nd year calc, discreet math, probability, and linear algebra in undergrad. This question was inspired by a TedEd video. Both my limited background in math and the oversimplified nature of the explanation at the end probably make this more mysterious for me.
The closest thing I can relate to would be how our model of computing is that that Turing came up with and how all computers we've created so far can't do anything that a Turing machine can't do.

There is a lot of good advice here, I would emphasize the fact that your enjoyment will increase dramatically if you find someone to play with. Even if you are absolutely terrible, jamming along with someone else can kindle a fire for music in a way that other methods cannot.
This is how I developed the passion to 'come home and play guitar until my fingers bled'.
Watch and learn from this TED talk by Victor Wooten (one of the most accomplished modern bassists and overall musicians). He talks about what it means to truly understand and enjoy the power of music, and not to see it as a chore.
Agree. People will always stereotype and generalize anything related to cultures, languages, and in the case of Africa, a whole continent.
For the interested, here are a couple of theories/subjects that opened my eyes and helped me understand better not just Africa, but many other different parts of the world.
-The Single Story -Orientalism. There's also a video with the author who coined this term, Edward Said
EDIT: Fixed links.
This is a great and short video explaining the three different tear types. As the video suggests, one type of tears is brought about to keep foreign objects/bacteria/etc from getting into our eye. I suspect that is the reason.
> It also seems to have remains in languages, as someone who learned English, I never understood the reason for "eleven" and "twelve"
Eleven in Old English means "One Leftover" Twelve in Old English means "Two Leftover" http://en.wikipedia.org/wiki/12_(number)
There is also a TED Teaching Video that talks about the Roots of English Words. http://ed.ted.com/lessons/making-sense-of-spelling-gina-cooke
If you're into writing, though, the Hero's Journey is an example of the natural flow of storytelling in epic scale.
Basically: Normal person living life. Normal person is called from ordinary life through some third party ordeal. Normal guy receives help of some kind (It's too dangerous to go alone! TAKE THIS!) from more wise person before going out and along. Normal person goes out into the unknown. Normal person faces trials. Normal person has a crisis - most notably, they consider giving up and residing to their fate, or just going back home entirely (this is what makes the characters human. Their mortality). The Normal person overcomes the crisis and receives what he came there for - now at the status of the Hero. Hero now has a result play out of his achievement (good or bad). The Hero makes the return to his ordinary, everyday place. He realizes that nothing is the same - he is now a Hero. The story resolves here and the plot lines are tied up once more. Everything returns to normal... But not quite.
It's an interesting study. Here's a good TED Lesson on the formula. It's a bit more refined than the Extra Creditz episode
Journey follows the exact same storytelling methods.
Awesome! Just make sure that you spend some time jamming with records you like and working out other people's lines in addition to scales. Also, learn the ways of Mr. Wooten
The unexpected math behind Van Gogh's "Starry Night"
>This fascinating short animation from TED-Ed and Natalya St. Clair, author of <strong><em>The Art of Mental Calculation</em></strong>, explores how “The Starry Night” sheds light on the concept of turbulent flow in fluid dynamics, one of the most complex ideas to explain mathematically and among the hardest for the human mind to grasp.

The free market works. Empirically that can be verified. Countries with more free market economies develop more quickly than less market-based economies.
As soon as government steps in to force one group to subsidise another, that creates harmful incentives that lead to growing dependency, less self-reliance and less will to achieve. Regulatory prohibitions against how people can use their own labour or property (e.g. laws against working through Uber or renting on Airbnb, or prohibiting developers from building developments with only 1 BRs) meanwhile just lead to opportunities for better meeting economic needs, based on the interplay between supply and demand being reflected in price and profit opportunities, not being exploited.
People underestimate the complexity of an economy and think cookie-cutter solutions that mandate one particular solution be used, based on a shallow analysis that looks at a tiny fraction of the many factors involved, are better than the complex market calculations that involve the interaction of millions of people. People fail to understand that the only way that a complex economy can be effectively be organised is through spontaneous order:
Carbohydrates are the umbrella term for different types of sugar. All of them raise insulin levels in the blood stream to higher levels than other foods. You are literally saying don't confuse this sugar with this other sugar.... i am not confusing them, they have different names for a reason. However, they are two different molecules of sugar. Sugar is not just sucrose, it is any molecule ending in -ose.
Here is a 5 minute ted talk that will catch you up to speed. http://ed.ted.com/lessons/how-do-carbohydrates-impact-your-health-richard-j-wood

Follow different journalists, follow international companies that do news in the US (assuming that's where you live), follow news from both sides. Easiest way to keep is to download a couple apps. I have Fox, Guardian, and BBC, among others that give me notifications on important stories from my phone.
Most of the diseases on earth don't even affect us, there's realistically no way something independently evolved on a separate planet could happen to be finely adapted enough to be virulent specifically for humans. It take a lot to infect a human, we have multiple very good ways of keeping things out. A Martian life form would definitely be incompatible with all life on earth even if it was a pathogen against organisms on Mars.
Here's a wonderful TED video where they explain what is needed for a virulent disease to evolve, none of which are found on Mars (to the best of my knowledge!)
I can understand how that sentence might sound scientifically illiterate, but I think that sentence is trying to sum up this Ted Talk by Nina Jablonski titled Breaking the illusion of skin color.
It's actually very common for competing businesses to be next to each other, because it's a Nash Equilibrium. It's not as good for the customers, but that's just tough.

We know very well how to make fat people thin. She just doesn't like that answer, so she ignores it.
Very criticism-averse people (like she appears to be) do this all the time--if they receive input they don't like or disagree with, they forget they ever heard it and as far as they're concerned, the question that prompted that input never got answered at all. Criticism-averse people have really selective hearing. They take in what they want to take in. Ragen's entire life at this point is built around denial of reality regarding CICO. She could no more accept a refutation of that reality than she could execute a fouetté.
How does this work? When i was a kid i used to do this and am prety sure its related to static electricity.
The experiment goes this way
You take a plastic chair sit on it with your foot not touching ground and then ask some one to take a cloth and hit the back of the plastic chair for 30sec and when the person sitting on the chair touches some one there will be a static shock. but the question i have is since according to Triboelectric Series plastic is way under and doesnt give up electrons and your skin does so you are positively charged but how is electrons moving from you to the chair and there isnt any friction btw you and the chair ????? am just confused can some one please explain this static charge? pleaseee
If you guys want to know what a static shock is then watch this video http://ed.ted.com/lessons/the-science-of-static-electricity-anuradha-bhagwat#watch
>A different way of thinking about what theories are is something like the following: usually, theories are expressed in the form of strictly universal statements, e.g. 'All ravens are black', and often relate to an underlying explanation of some physical phenomena for why they are unified, e.g. that the phenomena of gravitation occurs for all, with no exception to the object.
Unless I'm misunderstanding you, you're mixing up scientific theory with scientific law: http://ed.ted.com/lessons/what-s-the-difference-between-a-scientific-law-and-theory-matt-anticole

Here's a nice little TED video about sugar: http://ed.ted.com/lessons/how-sugar-affects-the-brain-nicole-avena
TL;DW: Sugar acts as an instant gratification signal to your brain ("yay!"-brain) but has detrimental effects to your body ("oh no!"-body). Your brain craves more of the happy and your body suffers for it without realizing.
Here is a visual of the amount of sugar in Coke: http://www.sugarstacks.com/
Haha. Cool. I thought I knew something. Nope :)

Just finished that unit. I found it a bit tricky because we use an abridged version of The Odyssey, so there are quite a few gaps. Basically, I taught them about all of the steps and used The Hobbit as an example. (They read it last year.) as we read The Odyssey, we identified scenes that correspond to the Hero's Journey and plotted them on a chart. We skipped quite a few steps since we read excerpts. Finally, I had the students write about personal "journeys," linking specific events to steps in the HJ. To make it more "epic," I told them to describe their obstacles as mythological beasts and their friends/family as supernatural guides.
If you're allowed to show movies, Labyrinth parallels the Hero's Journey pretty closely. There's also a Ted-Ed video that I found useful in introducing the concept. http://ed.ted.com/lessons/what-makes-a-hero-matthew-winkler Edited for typo
I practice my musical instrument nearly every day. It is my 20-30 minutes to relax. I also get to enjoy the benefits of playing an instrument. It's never too late to pick up an instrument or start singing!
while there are many ways of internally sending signals within the human body, we are only conscious of our neural signals. The fact we are not conscious of circulatory or immune signals is at least a hint. One of the primary issues is that they are far too slow. Even if one were to attempt to integrate these signals into our consciousness, they would be on such a time lag as to be more distracting than helpful.
As far as communication in forests, unfortunately there is more pseduo-science than science in that arena. Consider this ted talk: http://ed.ted.com/lessons/the-networked-beauty-of-forests-suzanne-simard I am welcome to specific evidence in this arena, but have mostly confronted new age dogma than meaningful data.
Shakespeare, once you develop the kinda "filter" needed to see past the antiquated language, is fantastic.

That sounds pretty normal. What my artist told me is that you want to wait a few hours to allow some of the ink to settle in, but until you shower, blood plasma starts coming to the surface of your skin and that can make the first shower a bit... delicate after sleeping overnight. You do lose some ink, especially in the first day or two. Sharing a couple links rather than explaining the details. Not aiming for info overload, but I thought understanding a little bit of the science behind tattoos might help to clarify what's going on with your body, and I thought including people explaining it a few different ways could help. Congrats on the new tattoo, and hope this helps.
