Just a thought: Albert-László Barabási is a famous physician specialised in network science. In his book Bursts he wrote that the location of a human can be calculated with 97% accuracy based on previous data (dropping to 95% if said human is a university student and it's friday). If you break this pattern of behaviour by walking or driving to truly random places, you will experience things you usually don't do in 97% of the time.
