Hi, This might be a dumb question, but I was wondering if pwp should be careful not to get too much exercise. . .This past weekend we took our bikes up to Minnesota & rode the bike trails. We rode 20 miles the first day and 28 the second day--8 of those miles in the rain!! There has to be another way to have fun! I was glad to see rain on the third mornng, and we headed home (in the car). I feel as if I'm using up all my dopamine when I exercise a lot. I felt alright . . .just a little exhausted by the third day! Any thoughts on this? . . . .Nancy Van Hook 54/5
