Exercise. Movement, strength, endurance…when these stop, everything goes. Consistent exercise strengthens muscles, bones, and connective tissue, builds aerobic capacity for heart and lung health, and raises dopamine levels for better mental health (improving mood and decreasing depression and anxiety). IMO, these benefits alone will improve longevity, battle chronic illness, and improve quality of life better than specific food choices. Plus. we have all heard of many of our grandparents and great grandparents living long productive lives, and I don’t remember ever seeing grandma counting calories or going lower carb….maybe it was because many of the occupations were blue collar hard working in nature.
