We use ever more energy to produce food and run vehicles, for example, and spend ever more money on medical treatments when excess food and inactivity make us sick.

Why do I run barefoot?
I got a new pair of running shoes - that are pretty rigid - and my feet hurt when I run in them for a while. I thought - "oh I could get one of those neato vibram 5 finger gorilla shoes"
and then I thought "but I want to go running now"
and so I did.
Among other reasons - you can feel the ground with every step you take. It makes an otherwise boring run around a geese-infested lake much more interesting.
