I run 6 days a week and ice skate 2-3 nights a week. Running allows me to both stay in good shape and do a lot of thinking; I've caught quite a few bugs during those morning runs. I played ice hockey in middle school and have loved skating ever since, so it's more for fun than health.

so true! walking or running or biking or swimming make for excellent designing or problem solving time.

doesn't replace solitude with a whiteboard, or other parts of the process, but definitely helps with getting one's thoughts in order and seeing around assumptions. i feel more creative when my blood is flowing.
