I am much older than you Bill and I am in the best of health. I don't trip over anything, don't fall off of anything. I do all my own work around home. Last year I put up 110 ft. of privacy fence entirely by myself. That's a whole lot of post holes and concrete. I was offered help but refused. Just wanted to see if I could do it alone. I am not gloating.Just after reading your post I realized how blessed I am, and how grateful I am to be able to do all this at my age. Hope you get to feeling better soon.
