Lifelong learning comes in many flavors. Last week I agreed to join a group of friends in 6 weeks of something called Zumba in order to improve our physical fitness. How hard could it be, after all? And the others joining aren't exactly spring chickens, though they are all younger than me. This morning, I looked at a few YouTube videos to see what I've gotten myself into this time. See the woman in the back row in the baggy, lime green t-shirt? I can ALMOST keep up with her....I think.
