According to the passage, which of the following is true?

Good health is not something you are able to buy at the drugstore, and you can’t depend on getting it back with a quick visit to a doctor when you’re sick, either.Keeping yourself healthy is your own responsibility. Mistreating your system by keeping bad habits, neglecting symptoms of illness, and ignoring common health rules can diminish the effect of the best medical care. Nowadays, health specialists promote the idea of wellness for everybody.Wellness means achieving the best possible health within the limits of your body. One person may need fewer calories than another. Some people might prefer a lot of easier exercise to more exhausting exercise. While one person enjoys playing seventy-two holes of golf a week, another would rather play three sweaty, competitive games of tennis. Understanding the needs of your own body is the key. Every one runs the risk of accidents, and no one can be sure of avoiding chronic diseases.Nevertheless, poor diet, stress, a bad working environment, and carelessness or abuse can ruin good health. By changing your habits or the conditions surrounding you, you can lower the risk or reduce the damage of disease.
