My suggested ten simple guidelines for everybody to maintain health, prevent disease, promote happiness and a longer health-span:
1. eliminate addictions you may have to smoking, alcohol, drugs, sugar, fat, salt.
2. get good quality sleep of 7.5 to 8 hours duration.
3. improve your nutrition by eliminating sugar, refined carbohydrates and packaged foods; eat real food; consume a diversity of nutrients. Likely you will need advice from a trained nutritionist to determine what is best for you. We are all different.
4. move your body with at least medium intensity regularly for at least 30 minutes per day or 3+ hours per week. Likely you will need advice from a trained professional to determine what is best for you. We are all different.
5. be happy; put a smile on your face; love someone and be loved; embrace life; focus on the positive and not the negative.
6. reduce your stress (psychological, physiological, environmental, emotional, physical).
7. set aside time for yourself everyday (no matter how small); explore the things you love to do; have a daily dose of pleasure; follow your dreams.
8. treat people as you would wish to be treated.
9. regularly spend time in nature and see all its shades, colors and shapes; breathe the fresh air; hear all the sounds; feel the wind, the sun, the water, the trees, the leaves; discern all the smells; see all the animals and insects; see how nature thrives under all conditions; and appreciate that you are a part of nature and depend on it.
10. recognize that your role in life has a greater value than simply what you do every day.
