If you seriously want to know, check out "People Watching" By Desmond Morris (HERE).

It goes through cultural differences too.

I personally started with this one and couldn't recommend a better one I think. It has the basics and a lot of explanations as to why we use the gestures we do.

I would recommend reading some books, but there are barely any body language books that have any form of actual scientific validity and aren't just people mostly making it up as they go along.

This is a good book on the topic of body language. It doesn't say how to read body language, but how scientists would go about using body language in experiments, what works and what doesn't. It is very well sourced and you will quickly realise that the majority of body language claims made by people are completely false.

This particular book includes facial expressions, vocal expression, proxemics, kinesics and eye gaze as its focus. It also discusses how these fields can be applied in interpersonal communication, education, mental illness, deception detection and relationship analysis.

It is a must read for people who want to learn more about the science that drives body language research.

By the way, in addition, I decided to read the "lying" section of this website you have linked and I guarantee you none of that stuff they list is accurate. Those things listed can possibly help you discover a liar under some circumstances but they are also wildly unreliable. I can definitely tell you the info in the "eyes direction" section is largely seen as incorrect by the top experts in the field. This is the same tired old list of things you find everywhere else. If you are getting information from things like this, you really need to do more deeper research. May I suggest this book (http://www.amazon.com/gp/product/B005UQCXK4?psc=1&redirect=true&ref_=oh_aui_search_detailpage) if you are at all interested in lie detection, as it collects data from studies done worldwide.

Not saying any of this website is false, because a lot of it has some merit. So just by looking at that section I am already wary about it. There's good information everywhere, as I am sure there is plenty of good info here, but you still have to be careful.
