Foreigners' health system has advantages. In the United States, it is true that almost every so-called healthy food indicates what it is good for. Much of it is advertising and hype, but eating more Badam is good for your heart. I believe it anyway. And the health system has a strong sense of prevention. When I was at school, I really got an email every winter to get a flu shot. This is just a microcosm. The propaganda and prevention of many diseases are indeed better than those in China, which we have to admit. Abuse of antibiotics should be much better in China in recent years, but the problem has been so long that people have accepted it imperceptibly. My colleague got the flu and recovered quickly. He said that he always recovered after taking cephalosporins. Here you are. . Whether it's physiological adaptation or psychological placebo or something, I can't say for sure. I just want to say that antibiotics don't work on viruses, which is unscientific! !
