I'm 84 and I have numb feet from breast cancer chemo 4 years ago, but I walk fine. I can't drive. In the grocery store, I push a cart. I got back Saturday from a 6 hour flight from Dallas. I did okay. I just keep walkng and clean the house , garden and enjoy mysef. I live alone on 22 acres in the California wilderness. (I do have son who drops by to help me.) I love watching foxes, bobcats, coyotes and other critters on a trailcam.
