I read about this recently in one of our Sunday papers. It is a site you can go to and they calculate how long you will live. You answer a few lifestyle questions and they give you an estimate on how long you will live. I came out with 83. Actually, I was amazed it was that good Neither of my parents lived to a very old age, I only go to the doctor when I'm half dead and tend to have a lot of stress. I thought they would say 60 something. So I was well pleased - Ha! They then, of course, give you a long list of things you can do to improve that number. I think the eons.com site is for 50 and older but they tell you where to go if you are 49 or younger. It's sort of crazy but it does make you think. Has anyone else done this?
