How do you know you'll be an empty nester in two years? Just because she's going to be 18 doesn't mean she's leaving the house. Ask me how I know!!! To address the issue of a healthy body, what are you doing to get in shape? Do you exercise as much as you can? When I turned 40 everything seemed to go downhill fast but at 61 I feel really great. I think having a mind that feels young is half the key and not knowing your medical problems I can't offer advice on that. Just do what you can every day and try to take care of yourself as best you can. We're all aging or we're dead!
