Because some people are not strong enough, but have to work hard. The physical examination clearly stipulates that you can apply for exemption from heart disease. Even if you don't know you are ill, there are always signs of physical discomfort. Sudden death does not mean sudden death. What kind of person doesn't understand his body, is irresponsible, and then starts complaining? Even without a medical examination, he may die suddenly at other times, because accidents are inevitable. The average probability of sudden death of so many students in the country is less than one in a million, right? It is essentially a case. Please don't rise to such a big level. Thank you. Plus, I never exercise at ordinary times, and my physical fitness is also recognized as poor. Although I seldom get sick, my strength is less than 55kg. Just one month before the physical examination, I spent half an hour training every day and finally relaxed. For normal people, it's just an attitude problem. The patient's sudden death is not responsible for himself.
