He sounds impressive, and I can get with you on being anti-ageist, but saying "The guy knows how to live" just reinforces the idea that everyone has their own take on what's important, and one size doesn't fit all. My idea of living my fullest potential barely overlaps with the apparent life of the person that you admire.

And that's fine; I read the point about "knowing how to live" to mean: he knew the life _he_ wanted to live, and lived it.

sneaky edit: if I could get life advice from any random old person, he would definitely be on my short list. The guy knows how to live.
