These are Hu Dayi's own three-word health-preserving sutras: keep your mouth shut, stretch your legs, zero smoking, drink plenty of water, have a good attitude, don't drink too much, get enough sleep, don't be too tired, be helpful, have a beautiful attitude, live in harmony at home, and live a hundred years.
Walking is the best way to exercise, which is not only simple and economical, but also an aerobic exercise. Aerobic exercise is a kind of light-moderate intensity continuous exercise aimed at improving physical endurance. In this exercise, the supply and demand of oxygen are in balance.
As for the intensity of exercise, it is appropriate to have a slight asthma when walking, but still be able to talk with your companions normally, that is, moderate and low intensity of exercise. No breath at all, the intensity is too low; I am out of breath and can't talk to my peers normally, which shows that the exercise intensity is too high. If you are panting after a little activity, it means that your heart has begun to age.
The most important premise of diet is to control the total amount. There is nothing you can't eat. Eating habits formed over the years are not easy to change, but the total amount is completely controlled.
Exercise plus a healthy lifestyle and mentality are the main reasons for health and longevity. In Hu Dayi's words, it is summed up as "it is not easy to be a hundred years old, not to get along with yourself, and to advise you not to cherish gold clothes and health; Oh, let a spiritual person take risks where he wants to go, don't get sick but pass; A good word you need to remember: as long as you are not dragged down by three words, you will live more than 90 if you don't live a hundred.
