When I was young and my mom asked in the evening what I'd done at school, I usually responded, We ate lunch... and we had recess... Now I'm in the twentieth grade, and lunch and recess -- coffee breaks and my commute bike ride -- are still the highlights of my day. I think my research is fascinating, but they make good coffee around here, and life usually looks better after half an hour on a bike.
