Bada found that most of the adult whales were between 20 and 60 years old when they died, but five males were much older. One was 91, one was 135, one 159, one 172, and the oldest whale was 211 years old at the time of its death. That whale, alive during the term of President Clinton, was also gliding slowly and gracefully through the Bering, Chukchi and Beaufort seas when Thomas Jefferson was president.-Alaska.edu
The oldest human being in recent history died at 122 and a half years old-- Jeanne Calment. This certainly puts to rest the claim some people make about Genesis 5 setting man's lifespan to a maximum of 120 years! (It was actually the amount of time humanity had to clean up its act before the Flood).
Anyway, if we can find a whale that's 211 years old, and that's just the one we found, what's to say it was not possible for a human being to live well passed 122 years old, considering how much smaller humans are than whales!?
