Modern medicine has proved that if you fidget and think too much, you will lose your essence, qi and spirit, which is very harmful to your body and mind. Some old people think a lot of things, which is really "the old people think for a long time". When something goes wrong, they will worry and think all day, and even think of the gains and losses of decades ago. After thinking a lot, their hearts will turn. It should be noted that this is harmful to health.
