Here's what I don't see: survivors that have a particular interest in "healthy" lifestyle.
Like the survivors weren't the kinds of people who smoked a pack of cigarettes a day, were drunk most nights in their 40s, nor weighed 350 pounds for a majority of their lives... so they weren't doing the obviously very unhealthy things.
But at the same time they weren't health fad people.
Yep. I once met a guy that was somehow just as proud of his two pack per day cigarette habit as he was his decades of sobriety because “at least it’s not heroin”. Dude had severe COPD and died from something lung-related a year later in his mid-50s.
People that declare themselves immune to death because they avoid [x substance] can have some insane ideas about diet, exercise, sleep, stress and [y substance]. Believing that the world is simple and controllable is a dangerous intoxicant.
