I think Toller Cranston knew about Yoga. I was sitting trying to pretend that I was sitting thus when our teacher said: Now...thread your right arm through your left arm; rest on your right shoulder and place your left arm on the small of your back.
I lie. I actually was on all fours but I might as well have been sitting thus. People around me dutifully folded up. Another woman and I shrugged.
Perhaps next time.
