Since
@Predator_SD made his post that is loosely connected to my post, I'll throw my 2 cents in and you know what they say, something is usually worth what you pay for it.
Living a long life is way, way overrated. Quality of life is the goal for me. YMMV.
Don't be reckless or a complete dumbass in life, but if you love cheeseburgers eat 'em. If you enjoy sucking a butt, smoke 'em if you got 'em. And if wine or bourbon is your thing, drink it.
Come with me to my Mom's ALF (assisted living facility) a few times and the last thing you'll want to do is live a long life. She's been there five+ years and I'm certain she's got at least five more.
My Mom will be 94 in a month and can do none of her instrumental ADLs and is losing her ability to do her basic ADLs. That is the case with many at her ALF.
Of sure, there is the 1 or 2 out of 100 octogenarians or nonagenarians that have a a high degree of independence, but I would hate to live a "longevity" lifestyle (you know, not doing the things I enjoy) to end up like everyone at my Mom's ALF. The percentages say you will if you live long enough.
I'm a percentages guy and the percentages tell me if I live a long life (I define that as ~85+), I will not run the Boston Marathon or kill that 400 bull elk and then drop dead the next week. It'll be a long and gradual decline that will lead me to my nearest ALF. That's not my choice for me or my family. Again YMMV.

P.S. This was 20 years ago in Boston. I had a coworker whose total cholesterol was 400+. Off the charts high, right? His doc said lifestyle changes like mentioned in the original post can only reduce his numbers by about 10% and the genes you got are what determines your longevity.
