Kathie Tollifison, Yes, where are they getting all that energy? I keep forgetting, I can't do the things I used to. I would guess the super exercisers just haven't been hit by the fatigue fairy yet. I think of how nice it would be to take a walk or do some shopping or volunteer work and then I get up on my feet and nearly fall down from my bad balance. Everything tires me out. I was playing tennis two years ago and worked a full time job. It's impossible now. Glad I didn't complain about all those PDrs that weren't trying and needed to stay busy! Ha. I sleep 8-9 hours a night too. Everybody is affected differently. Patricia 60/3 yrs.
