ok. good explanation. I managed to commit to exercise during PMR. I only had a couple of months prior to diagnosis that was miserable. I do believe it helped. The fatigue has been my issue while on prednisone and after. My interest peaks when that subject comes up. But, I also realize, that going from my 60's to my 70's has been a bit more of a challenge than any other decade. 70's to 80's is going to be like freewheeling downhill.
