I've wondered about this for a while, without being able to come up with an answer.
Is there a body part that single-handedly determines the direction we're walking in? Is it a group of body parts that make us "steer" when walking?
I took a look at the behavior of some body parts while walking, and I came to the conclusion that:
- it's not the direction the feet are pointed to, as you can turn them in or out while maintaining your path
- it's not your head, of course, as you can be looking at any direction while maintaining your path
- it's not your hips either, as you can move them freely without changing path (although I wouldn't suggest trying that in front of people)
As much as this sounds like a silly question, I still haven't been able to get to an answer. Any input is appreciated.
