Mother Nature provides chairs - logs, stumps & rocks. I've used all of them for chairs at one time or another.

But like WearBear said, it's hard to do all that good stuff if you're old, sick, and/or injured. In spite of the problems my body has, I don't sit for hours at a time - I don't know anyone who does. But with my bad knee I can't stand for as long as I used to, so I'm sitting more now. But at the very least, the cats make me get up & do things.

And no way am I going barefoot - there's well over a foot of snow outside & the floors are cold!
