Okay, it said 86 for me - not bad considering I'm pretty overweight and don't exercise much. On the other hand, I seem to come from good stock - a lot of my rels lived into their 80s and beyond. My dad died at 87 and my grandmother at 85, and they were overweight too. Scarcely a thin person in my family, actually.

I'm sure I could improve my odds with a better diet and more exercise - up to 6 years if I lose a lot of weight - but getting started is always the problem.
