As the saying goes: "Young couples are old companions, and old couples are old companions day and night." Kindness, friendship, mutual care and long-term happiness will surely lead to a long and healthy life and delay aging. People are old, leaving work and collective life, and children are married and not around. Therefore, elderly couples need to care for each other, understand each other and love each other like young people.

However, if they are separated or quarrel frequently, and their feelings are not harmonious, they will be in a state of sadness and resentment for a long time, which will lead to nervous system disorder, decreased immune function, hypertension, coronary heart disease, arteriosclerosis and even promote the occurrence of cancer.

Facts have proved that love and harmony between husband and wife are beneficial to health. Research by experts from New Mexico Medical University in the United States shows that people who have no partner will generally die earlier than similar patients with partners after being diagnosed with cancer. The rate of people who are found to have cancer and still live for five years is more than twice that of bachelors. This may be because couples care about each other and can get more comfort from their spouses after illness. If the old couple are separated at this time, it will be harmful.

There is such a health care proverb: "Loyalty is the foundation of longevity, and kindness is the source of happiness". This famous saying has its scientific truth, especially in the health care and fitness of middle-aged and elderly people. The old couple respect each other as guests, treat each other sincerely every day, live together kindly and happily, can resist various diseases and are not easy to get sick. Even people with certain diseases, such as tuberculosis, hepatitis, hypertension, coronary heart disease, diabetes and so on. As long as there are relatives to take care of, full of love, plus reasonable treatment, it is more conducive to rehabilitation. The secret is that patients often get benign stimulation, so that the functions of cerebral cortex and neurohumors are in a balanced state, thus maintaining the functions of various organs and enhancing the immunity of the body.

If elderly couples are separated, they can't take care of each other, get no benign stimulation, and all organs of the body can't be maintained normally. Therefore, the separation of elderly couples is not conducive to health and anti-aging.
