Modern people are generally under great pressure. High-intensity work every day makes many people's bodies overdraw, which will cause physical problems for a long time. The ancients ate coarse grains, while modern people eat more flour and rice, which leads to worse and worse physical condition.
Modern environmental pollution is serious, which also leads to the speed of medical development can not keep up with the speed of disease. I think that no matter how high the medical level is, we can only be healthy if we take good care of our bodies. As for medical conditions, it is only a means to remedy our health. After all, it's too late to mend.
