Nice little piece on yoga in prisons in today's NYT:
“There are a lot of butts in the air,” said Billy Scruggs, 33, who was convicted of statutory burglary. “But after the first time I did it, I saw how much it relaxed me.”True that. And don't worry about all the butts, Billy. You'll get used to that.
