I think elderly is someone in their 90's. My DH is going on 77 and I will be 72 years old in October and we certainly are not elderly. We travel all over in our RV and camper, we have worked on our house and yard, painting and fixing tons of stuff without any help at all. We maintain a huge yard filled with flowers, he still rides his motorcycle and I quilt and knit and sew and cook and bake. We are very active people. I have observed that when you start getting into your 90's life does change a great deal. My two aunts are now 94 and 97 and they live in assisted living apartments. My hair is whiter than the Aunt who is 94.
