Explanation:

1. Whether any food should be digested first (suitable for you personally), as long as how much you eat can not only be digested and absorbed, but also be converted into energy (exercise consumption) is the way to eat.

2. Any exercise (including brain power) is consumed on the basis of diet (excessive sweating) until you sleep soundly at night, so as to achieve the best effect of combining work and rest. This is the way to exercise.

3. Replacing any cosmetic perfume with the fragrance of natural flowers and plants, and replacing health care products with improving one's own immunity, is the way to keep in good health.

4. To protect and strengthen the kidney, eat less vitamins in protein and spend some anthocyanins on bean products. This is the way to live a long life.
