Life expectancy in Italy is about 5 years longer than in the USA. So maybe a quad a day doesn’t hurt everyone.
We are in our mid 70s. My wife has maintained her girlish figure through exercise (about an hour a day) and diet. Her bmi is on the very low end. She never eats fat, red meat, or sugar. She eats oat bran every day. And all her coffee is filtered. Her doctor says she has cholesterol issues.
I am the opposite. I eat marbled red meat several times a week. I don’t have an oat bran regimen. I exercise maybe 5 times a week for 20 minutes. And my bmi is at the other side of the spectrum. My coffee is virtually all unfiltered espresso. My doctor marvels at my cholesterol numbers. He says they’re great. I have quarterly tests, so it’s pretty closely monitored.
My point is that all of this stuff is tied strongly to your genes. Your genes determine the range of possibilities. Environmental and behavioral factors determine where you are within that range. One guy’s got diabetes. Another has high blood pressure. Another has cholesterol issues. One’s a smoker. One’s a marathoner. When our number’s up, we check out. Mortality is always fatal.
