Hooray for Old People at the Gym!

I have been (so far successfully) trying to offset Holiday eating by increasing gym time from my paltry weekly visit back to 3/4 times a week. I go in the mornings when it is not very crowded, and there are many old people there. I don't mean slightly old people, although there are some of them there, too. I mean old people in their 70s and 80s, possibly older. I see them industriously exercising their muscles and doing cardio, and I am impressed! Husbands and wives come together and exercise parallel to one another. They are faithful, consistent, motivated, and cheerful! Oh, to still be going to the gym when I am 80, keeping the muscles moving.
