RE: brainiacs and bicycling.

DH is a bicycle commuter and the computer dude at his place of employment. He comments that he just THINKS better on those days he rides (most). Or to put it another way, he feels the bike makes him smart and the car makes him dumb.

And wasn't it the ancient Greeks who believed that a person should have both a fit body and a fit mind? (You just can't go wrong quoting the ancient Greeks...)
