My 23 year old GF wants to go to yoga classes, and wants me to go with her. I wouldn’t mind going once a week, but this is five days a week, and I’m over 60. Of course she has to have the lycra gear to go with it and a couple of changes for different days. I went with her for the first lesson and I was sore the next day. It might be fine for Thai women, but not for me. The GF is putting the weights on me to sign up (and pay for her as well).
If it makes you feel better, most people who sign up for Yoga classes never go the whole distance. However, I think you should adopt the Empty Wallet position, followed by the Close the Door on Your Way Out pose. Ferdy, you are being taken to the cleaners while in the Lotus.
