Do you all find that commuting by bicycle makes you more likely to hate your fellow man? Since my "commute" is less than a mile I usually just walk it, and it's great and peaceful and I get to work in a good mood. I've just started riding my bike instead, and now I get to work in a bad mood, hating all those stupid stopsign-running jerks with their cell phones and their SUVs. They stop for pedestrians, but for a bicycle with the right of way? Forget it.

Maybe this explains that heart attack statistic from the other thread.
