Forget about all that worry, reading, supplements, and stress to stay alive. When the time comes there is nothing you can do about it. Its all in the genes you inherited. Dogs cats, deer in the woods, people that abuse themselves etc don’t worry about a thing. Ignorance is bliss.
I swear all these medical adds on TV have people paranoid and worried al the time. People think their human maintenance free self healing body is like a car. Important to change the oil every 3000 miles, Plugs air filter every 12,000 miles, watch your oil pressure and water temperature bla bla bla. In fact only two countries allow medical adds on TV. They will probably put a stop to it. Like cigarette and alcohol and firearms commercials.
I’m 74, and can pass for 55-60. Easy. I don’t like and rarely eat fruits or vegetables. I eat all kinds of things health watching people would not eat. Plenty of carbohydrates. And I’m not fat and still have all my blond hair like my grandfather did. My grandmother had brown hair into her 80s. People don’t believe me when I tell the my age. One time I had to show a barber my drivers license to prove it.
