What is it you do to keep fit...

Primarily cycling, 4,000-5,000 miles per year.

No reason you can't keep both mind and body healthy, really...to neglect either is a shame

and thats exactly why I continue to complete night schooling to get a designation in my field of work

Run a mile, then: jumping jacks, push-ups, crunches, and some twisting/stretching moves. I do this 5 times a week. Next, I plan to buy an elliptical and maybe some weights.

To be honest, I don't like exercising. But I force myself just to stay healthy.
