Whether the sleep quality of the elderly is good. Sleep accounts for 1/3 of a person's life. Men over the age of 60 still guarantee to sleep for 7 hours every night and can sleep until dawn, indicating good health.
Whether the legs and feet are flexible. Some old people will have pain in their legs and feet, and their limbs will not move very much. If the elderly over 60 are still flexible in legs and feet and can maintain a certain amount of exercise, it means that they are in good health.
Whether defecation is regular. The regularity of defecation in elderly people over 60 years old shows that intestinal peristalsis and renal function are good. In addition, good appetite and good memory are also the criteria for investigation.
