Clara, I really appreciate you posting about your activities. I've concluded after reading your comments and those of others, I've been taking it a bit too easy! I ate dinner with my two feet on the floor last night, and I think that did me in! I plan to try to move around a bit more. I just wanted you to know you are motivating me!
One other thing - my back is sore and I don't even have back problems. I believe it's because I'm not moving around normally. Maybe it's hunching over, not sitting up straight, or just not moving around enough, but it's not easy on the back!
