Falls are a major cause of fractures in the elderly, and preventing falls in the elderly can reduce the occurrence of fractures. Many old people accidentally fell down and broke their bones because the room was dark at night. Therefore, there are elderly people at home, so it is recommended to install floor lamps and other equipment at home. In addition, with the increase of age, the muscles of the elderly are shrinking, normal muscle tissue has become adipose tissue, and the recovery ability of the elderly will be reduced accordingly. Therefore, for the elderly, muscle exercise can promote the improvement of their resilience. In special circumstances, the central nervous system can give instructions in time to make the muscles contract quickly, thus preventing the elderly from falling.
