Living in an immediate post ice age environment in small hunter gatherer groups and an infant mortality rate higher than 50% had some effect on "left expectancy" too.
There are vegetarian exercise freaks who drop dead from heart attacks. And relatives on my father's side in Kentucky lived into their nineties on a lifestyle of hard work and a diet that featured savory baked corn bread slathered in butter, buttermilk biscuits seasoned with salt cured country ham and red eye gravy, fresh chicken double breaded in flour and fried in lard, turnip greens cooked in bacon fat, green beans the same, fresh and home canned tomatoes, and corn, corn, and more corn.
Frankly, I think genetics plays a far more powerful role in how long a person lives than it's given credit for. And as long as someone eats in moderation when hungry and remains active their chances are as good as nature will allow. But bottom line, nobody gets out of here alive so you may as well do your best to enjoy the time you're given. And that includes eating what you crave when you crave it. If that balloons you into morbid obesity then adjustment may be required.
“Life” expectancy. Left expectancy is always expecting Leftists to preach people into hunger and sacrifice for the “good of all”.
Yes, I was being a little facetious. I know that life expectancy is determined by a lot more than simply one’s diet.
I’d agree that genetics has a lot to do with it, and that if you live long enough, you’re going to die of something. I don’t worry too much about what I eat, but try to stay fairly active. Am I capable of doing what I could 40 years ago? Hell no, but I do get through each day without (much) assistance.
