A recent study by George Washington University found that choir singers are healthier, less depressed and look younger than ordinary people. This is because singing can promote the production of dopamine and help relieve stress. Moreover, most of the songs sung by the old people are learned when they were young, and they can follow the songs back to the happy youth in their memories and find the feeling of youth. Singing often can also increase lung capacity. When the oxygen content in the blood increases, the aging rate will slow down. It's best to choose a light and pleasant song. Singing two songs every day will bring a good mood to the day.

Buy big when you have time.

Researchers in marketing and psychology at Golden Gate University in San Francisco found that before shopping, people will have rich psychological activities, naturally imagine their future use of new items, and at the same time imagine their future new life, which will make people feel happy and happy. For the elderly, even if they go to the vegetable market to buy food every day, they will have a sense of satisfaction in arranging their lives and taking care of themselves, and reduce negative emotions such as "being old and useless". The study also found that shopping can promote the brain to release the happy hormone dopamine and keep the body in a positive state, so it looks younger and more energetic.

Keep working.

A new study published in the American Journal of Health Economics found that delaying retirement does not affect people's enjoyment of a happy old age, but makes people feel happy, look good and look young. On the one hand, continuing to work can better keep the brain and body active and reduce the risk of cognitive impairment; On the other hand, people will have a fixed social circle at work, which can reduce the possibility of social loneliness. Therefore, within the scope of physical and energy, even at retirement age, you can take part in some jobs that can give full play to your residual heat, enhance your sense of value, reduce your sense of "uselessness" and help you stay young forever.

Have confidence

Studies have shown that people with pursuits and beliefs rarely suffer from depression, have stronger immunity, have lower incidence, live at least seven years longer than those without pursuits and beliefs, and look younger and have better spirits. Many studies have confirmed that there is a correlation between belief and longevity. The belief mentioned here does not necessarily come from religion, but can also be an optimistic attitude towards life, a source of inner strength, or even a strong interest, which will provide strong support for life and encourage people to keep learning, pursuing and making progress. Many people think that they can live well without faith, but people with faith will understand the meaning of life more thoroughly and keep a young, pure and positive heart inspired by this positive energy.
