I'm a sedentary fellow, no doubt about it. Aside from my obsessive reading, I was a TV zombie as a kid. I wasn't only sedentary, of course. I loved roaming the woods along the creek near my house. Schools teach body literacy even more poorly than they do anything else.
Movement is discouraged, stretching frowned upon, and comfort almost completely eliminated.
I visited it a few years back and was revolted to see that my memories were of a much milder oppressiveness than that of the new reality. How can teachers stand as mentors, friends, advisors, and models if they are, almost literally, guards . As I said, I'm a sedentary fellow, made more so by my arthritis and occupations. However, my physical therapist finally convinced me to use a kitchen timer and get up every twenty minutes to stretch and get some movement. I'll even do this in class now, and damn the funny looks.
