P.U.

I just took a walk around the parking lot and now I'm sitting at my desk bearing the oddly overbearing odor of "eau de kids apres recess." In junior high, I used to be a grade school teacher's assistant and I remember almost being suffocated by the funky fresh odor of 25 little kids coming in from playing in the "fresh" air. What is the chemistry behind recess reeking? We may never know, but it persists into adulthood according to my personal findings.
