If I can stay healthy at age 82, with no diabetes, no heart issues, no prostate issues, no kidney issues, no signs of dementia, and enough stamina to mow my lawn with push mower during Florida summers, I think I must be doing something right.
Very briefly, lots of fruits & vegetables, less refined grains, less red meat, more fish & chicken, 1 multi-vit pill daily, and moderate aerobic exercise 5 days every week.
