First, whether the elderly live a long and healthy life is related to heredity. Genetic inheritance has a great relationship with everyone's health. It has been studied that there is an old man in his family 105 years old, and relevant personnel have also done experimental research. The results show that heredity can really affect people's life span. Besides heredity, other things in life will also affect health. If everyone's inheritance is not very good, then we should pay more attention to the quality of life, develop some good living habits and maintain a healthy diet, which can also make everyone's body live longer and become healthy. Even if some people have better genes and will endure, it is difficult to live long if they don't pay attention to their health the day after tomorrow.
Second, the factors that affect people's longevity and health, besides heredity, will also lead to people's longevity. It is also good to have a good living habit. Some people like drinking and smoking very much, and even smoking several cigarettes a day is not good for everyone's health. Smoking hurts the lungs, drinking hurts the liver, and smoking and drinking a lot will definitely lead to people's health getting worse and worse. Such people are also short-lived, so they must cultivate a good life. Stay up late every day to improve immunity, otherwise working for a long time will easily lead to sudden physical death and other diseases, which is also very harmful to the body. We should also have a regular diet, eat some healthy food and keep a healthy attitude. People with a good attitude will live longer.
