Meeting some friends at a local joint, I arrived early and ordered a margarita. The waiter, an imposing figure of six-foot-plus with a smooth bald head, gave me a wink and a friendly smile. As the place sat empty, we chatted a bit. Think Mr. Clean without the gold hoop. Somehow yoga and flexibility popped into the conversation . . . Imagine that. This guy pushed two hundred fifty pounds of trim and fit so when he mentioned his first yoga class I grinned.
