Ahh, age-shmage! 63 ain't that old. Give him twenty more years and then say his age might have worked against him. Those Inuit guys eat lots of fish, one of the most nutrient dense foods.
If you live a healthy lifestyle, you don't get "old" until you're almost 100. Only smokers, alcoholics, unhealthy eaters and couch-potatoes get old in their sixties. Age is relative.
If people really wanted to live to be 120, they could. A few have, maybe because they didn't listen to society telling them that people don't live that long.
Sixty should be thought of by mainstream society as "just over the hump"! People just have to wake up to the reality that we are not living anywhere near the healthy lifestyles that we could be living.
