My maternal grandfather lived till he was 97. He drank a quart of vodka with breakfast, a quart of rye with dinner, assorted beers in the course of a day, for at least 30 years....He ate one meal daily, continuously, from waking till sleep. Fats, sugars, whatever pleased his eyes. At 90 I took him for his first physical in ten years, with a straight face, the doctor said he was pickled. He chased women until he was 96, but he couldn't always remember what do with them after he hit 95. He died after slipping in the shower, banging his head against a wall, developed an aneurism in the brain, passed in his sleep that night, painlessly. He fought in 6 wars,...bred mastiffs as a hobby, loved horseback riding and hunting.... No one can explain how or why he lived so long. I can't remember him without a cigar in his mouth, a pack of Lucky Strikes in his pocket. He smoked pot and opium since a child. ...His marriage was arranged... There is no logical explanation why or how he lived so long in relative good health.
Trust me, I do understand where you're coming from, to a point...two quarts of booze daily and one meal attests to genetics, which isn't (yet) controllable. Momma, and Dad for that matter, even as he's passed on, along with my other ancestors also indulged whatever suited them and lived to ripe old ages (88+), several quite a ways into their 90s, though they didn't lead quite as profligate a lifestyle as you describe your grandpa as having lived.
Yours, others' and my ancestors notwithstanding, with my OP, I'm focused on a lifestyle/-span that isn't exceptional and on the merits of doing things in a "sensible" way so as to obtain as much "good life" as one's genetics can sustain. I'm well aware that there will be exceptions, and given the size of the population, the quantity of them will, as an abstract figure, be large-ish. That said, I think that if one's got really good genes, one will enjoy the "good life" -- "good life" meaning one isn't dependent on others to maintain oneself (cook, eat, move about, dress, bathe, think, and the like) -- longer by living fit and healthy and working with, rather than trying to fight "Mother Nature."
If I had to attribute the "old folks'" longevity to anything, I'd cite physicality and eating "real" foods rather than the processed and "
enhanced" (be it with preservatives, colorings, or anything else) stuff that's almost hard to avoid these days. Genetics, of course, play a role too, but I think the role genetics plays is to "define" the upper limit of what's possible if one "lives right." Obviously if one's genetic "salad" is such that one's likely to make it past 95 with a quality lifestyle still regardless of what one does, one has more options than do folks whose upper limit might be 87.
FWIW, this thread was inspired by a woman whom I saw at the Christmas party I went to the other day. I haven't seen her in person for some 12 or so years, but I've known her since we were in high school. She's two years older than I, which puts her in her early 60s, yet she looks like she's not a day younger than 75. She's due to get her second facelift in a few weeks. Truly, I felt bad for her when I saw her.
When we saw each other, she said, "Dear, God. You look amazing," and, recalling her as a full-on "movie star" hot woman, it struck me how awful I felt not being able to say "so do you." She was a great looking girl and a gorgeous woman, even in her early 40s when she first started having "this and that" tightened up, sucked out, pushed in, etc...I remember when she got some "minor" work done and I wondered had she lost her mind, and then she had a facelift in her early 50s and I decided she indeed had lost her mind. Unfortunately, it's coming undone and she's having to have it "updated," and frankly, her no-nip-tuck sister, whom I saw a couple years back, looks great, better actually, and not just for a 60-something woman. What's the difference between them? "Suzy Surgery" lives a very indulgent lifestyle, whereas her sister lives lavishly, but healthily. (Strangely, "Suzy" didn't get breast implants, yet that's the only work her sister got.)
Of course, those two aren't the only friends/acquaintances I've encountered from my youth. Other than my closest friend (the party host) from back then, most of them look their age, but they don't look awful for their age. My running buddy and I don't look our age, but we've both been health/fitness junkies since we were kids. We molded ourselves into "jocks" at an early age and found we better liked the responses we got from others as jocks than that which we got as the gangly boys we were before discovering the gym and healthy eating. We stuck with it, and it appears to be paying off.
