Depends on where you live - I grew up in the countryside of the Netherlans, which has excellent biking infrastructure, almost no traffic, and a calm environment in general. Biking to and from school every day was very good for my mind.
Well you are lucky. Somewhere between bad drivers, bad roads and the lack of any flat distance whatsoever, it's impossible for me to leave my mind off the road for any length of time when cycling.
Oh okay then, the main bike lane in my area has regular curves and vicious intersections, with people/kids walking by. I don't stare at girls anymore since I don't like kissing trees that much.
