Old people often say that if there are no diseases and disasters in their later years, it will be a blessing accumulated in their previous lives. When I was still in junior high school, my mother urged me to wear warm clothes and eat hot food every day after autumn, lest I catch cold and freeze. Checking whether I wear long pants is something my mother must do every morning. She often says that I don't wear thick pants to brag now, and I have been sick until I am old. Therefore, in old age, in order to have a healthy body, the elderly always go to parks or squares to exercise and improve their immunity.

The health of the elderly is not better than that of teenagers. Their bones become loose and their physical endurance is weak, so they can't do strenuous exercise. Therefore, low-energy sports are more suitable, such as Tai Ji Chuan, sword dance, square dance, yangko and so on.

Tai Ji Chuan is a national intangible cultural heritage, with China's Confucianism and Yin-Yang Theory as its core thoughts. Tai Chi is gentle and powerful, slow and orderly, and one stroke and one style is integrated into life attitude. Through Tai Ji Chuan's every movement, he not only relaxed his muscles and bones, but also achieved the function of regulating his internal organs, which not only cultivated his self-cultivation, but also strengthened his body. When you play Tai Chi, people will become very calm, that is, the so-called abdomen, which is a very suitable exercise for the elderly.

As early as ancient times, there was the word "sword dancing", which we are familiar with, refers to sword dancing. Sword dancing is a combination of rigidity and softness, with sharp attack and elegant posture in fencing. Sword dancing can make people agile, have a more free and easy attitude towards everything in the world, and have the mind of a hero swallowing mountains and rivers in the novel.

Sticking to exercise and fitness will enhance the immunity of the elderly, and having a healthy body will make the elderly suffer less from diseases and have a happier old age.
