Hi, I am new to this site. I just read your note, and I too am the same age. I find that I have not been able to get around because of the weakness and that in turn is causing my muscles to atrophy. Seems to happen faster now because of age. I know I get fatigued a lot and need a nap in the afternoon. Seems like trying to use the muscles makes me more tired...but have to keep on trying. .....I live in an active community and the people here are same age doing circles around me. Tough place to live....
