Depends a lot on the lifestyle. A few of my relatives managed to stay relatively fit over 70 with a relatively active lifestyle and probably some luck in the genetic makeup (they do need vision aids, but can manage fairly OK with them). I'm from Europe, but I heard that Japanese have a comparably high life expectancy, which likely results in better overall health in all age groups. I'm sitting in front of a computer all day, so my chances are probably not as good in this regard if I don't change things. But I guess this kind of insight is news for few people around here.
