Those of you who know I was born in 1966, and can do math, know that I turned 40 in 2006. Which might be slightly early for a proper mid-life crisis, but I had one anyway. No, I didn't dump my spouse or buy a stupid car or get plastic surgery or move to Barbados (though that last one sounds kind of fun, now that I think about it).
What I did was start taking a Bikram Yoga class. I had taken a few before, and had been thinking about starting to take them regularly after my belly dance class went on permanent hiatus. But I had also been thinking about learning pole-dancing, or Irish step-dancing, or some kind of circus arts.
