Laughter is a peaceful state of mind, a kind inner expression, and it is also the time when endorphin secretion increases in the body. When a person's mood is in a normal state, he will show a peaceful psychological effect in the conversation with others, and show the goodwill communication between people with a smile. Good and evil is the psychological function of human beings and the result of primate evolution.
People naturally love to laugh, but few people know that laughter is also a good fitness exercise. Every time you laugh, there are about 80 muscles involved in the exercise from the face to the abdomen. Laughing 100 times can exercise the blood circulation of cardiopulmonary function, which is equivalent to rowing 10 minutes. Unfortunately, when people reach adulthood, they only laugh 15 times a day on average.
Laughing about 400 times a day is much less than when I was a child, which is at least a regrettable loss to my health. As long as you laugh, the muscles of your mouth and cheekbones will laugh with you. Lift your mouth and eyes up to prevent facial lines from sagging.
