That research is correct. After age 45, exercise is more beneficial to good health than diet, vitamin and other supplements, or any other snake oil out there.
Absolutely. From about age 23 to 50 I did absolutely no exercise other than walking and last year I finally took up running and holy cow what a difference. For years i felt like crap, tired all the time, and now it’s like night and day, like getting rocket fuel in the body. Everything has improved 1000% even my hearing which shocked me. Once that blood flow improves, everything is different, everything changes for the better. Every person out there who is out of shape, constantly has health issues or is tired all the time, or is depressed, got problems with sex - Try exercise it will absolutely change your life around I kid you not.
