Under the background of aging, the disadvantage of making and broadcasting health care programs for the elderly is that the causes of serious physical problems are often attributed to some small habits in life, such as what to eat and what not to eat, which is misleading and easy to ignore the real reasons and more serious factors. After watching these programs, middle-aged and elderly people often blindly think that some serious physical diseases can be avoided or corrected by adhering to or changing some small habits in life, which delays the remedies that have really been scientifically studied. In this sense, health programs are harmful. It is suggested that middle-aged and elderly people watch less such programs and learn more scientific medical knowledge from real doctors. Is keeping healthy a verb or a noun? It originally refers to a medical activity to maintain life, enhance physical fitness and prevent diseases through various methods, thus prolonging life. Raising is nursed back to health, maintained and nourished. Life means living, surviving and growing. Health preservation in the modern sense refers to actively maintaining physical and mental health according to the laws of human life process.
