While I might not have a scheduled regime pertaining to physical workouts, I definitely agree with this article. About three times a week I bike ten miles to the state park, if I'm not biking I take a long swim down the shore (my parent's own a lakefront house) Also I spend pretty much every day at my parent's and there are three mega flights of stairs to the lake which I'm up and down all day.

I know for a fact that physical exercise helps with mental clarity, because in the winter there is a notable change in my inspiration and creativity, to the point that this year I picked up some cross country skiis to alleviate some of that. (If you've never done it, then let me be the first to tell you that it is grueling until you've been out there a number of times, it works out muscles that no other form of exercise does)

Also a quick question...do you eat meat?

I stopped this year, and I don't even think exercise competes with the jump in mental acuity I've had since then.
