This is an interesting web test that (supposedly) reveals your virtual age and personal life expectancy vs your biological age the average life expectancy for someone like you. The questions and how the answers effect the outcome seems to prove out a lot of MrPlum's theories on health due to lifestyle, diet, medications, stress, meditation, etc. It's very interesting in that it uses a sliding scale that you can move up or down to see just how much a certain behavior affects your life expectancy.
With a biological age of 59, and with honest answers I got a virtual age of 66.1 and whereas the average life expectancy of someone with my sex, race, and family history would be 78, mine, due to my lifestyle is 70.9.
MrPlum, I expect you will score a life expectancy somewhere in the 90's unless you have a poor family history.
If anyone wants to give it a try... here's the link. Answer honestly and good luck!
