Modern people live in a stressful environment. They can't eat well, sleep well, the environment is polluted, the air is not fresh, and their bodies are basically in a sub-health state. Moreover, everyone's system is different. If parents don't take good care of their bodies when they are pregnant, the children born are inherently weak, so we need health care the day after tomorrow. Health care can keep your body in a relatively balanced state, enhance our resistance and make us less sick. So now everyone pays more attention to health.
3. No health equals zero. Only a healthy body can bring us endless wealth.
