Four things that really matter to longevity:
1) The elimination of genetic triggers that drastically lower lifespan. Innovation may accomplish this in our lifetimes.
2) A metabolic thermostat that is easy to calculate. If a person is barely out of high school when they marry and have children, then are a grandparent in their early 40s, they most likely have their thermostat set on high and will not live much past their 60s.
However, people who don’t marry until they are in their 30s and have children later as well, and are only grandparents in their 60s, are a good indicator that they will live into their 90s and beyond.
3) Those who avoid having serious diseases in the major age windows for those diseases. That is, particular diseases occur most frequently in people of certain ages. If you avoid these diseases it usually means that you are healthier than is typical.
4) Self-control and not engaging in risky behavior.

Huh?
Yeah, but Alzheimer’s Disease comes out of nowhere.
What about Dementia and Parkinson’s?
Most “doctors” are absolutely clueless about these types of things, are they not?
I don’t know, I have a sister and BIL who eat like sparrows at Canyon Ranch: though they’re in their mid-50’s they look a good 20 years younger. But I have 2 other sisters who were married with kids in their early 20’s and were grandmothers by 50. Could their prospects be that different in one family?
(I’m active and healthy, but have probably already eaten enough for someone a good decade older than my age!)
