How the way we walk can increase risk of being mugged.  The mind-body problem in the real world? “There is school of thought that the brain only exists to control movement. So perhaps we shouldn’t be surprised that how we move can give a lot away. It’s also not surprising that other people are able to read our movements, whether it is in judging whether we will win a music competition, or whether we are bluffing at poker. You see how someone moves before you can see their expression, hear what they are saying or smell them. Movements are the first signs of others’ thoughts, so we’ve evolved to be good (and quick) at reading them.”
