Very little carbs and sweets, and always a morning secret drink mix of healthy cleansing and heart healthy natural remedies. Biggest vice is a daily mexican coke with real sugar with lunch. Eat loads of meat chicken and fish and veggies. I feel better at 77 than I did at 65. Also I have not had tap water for years and use only Himalayan pink salt. My wife and I never get colds or have had covid and have been very active.
