Is it better to be a security guard in a school or a nurse in a hospital?

I have been a security guard for 8 years. Now I'm 32 years old. Although I worked as a security guard for 8 years, once I left the security industry, I really couldn't find a suitable job. Nowadays, there are many high-rise residential quarters, so it is easy to find a security job, but it is difficult to find a suitable one. Because of the high requirements, security guards should always set up posts, and outsiders should be invited to call the owners with smart devices when entering and leaving residential areas. Intelligent prosecutor (you can't doze off if you change every hour on the night shift. With the prosecutor, you want to find a place to rest, hehehe, you will be fined) are the most harmful to your health, and easy to age. As a security guard, many factories and residential hotels are very taboo to have people who have worked as security guards. Why did you leave your last property company? That's the problem. You said you quit, and if you want to change places, you won't be a security guard! Even if you have a safety certificate, what's the use! There is a limit to the age of factory security. No one under the age of 35 is allowed in. And height. In some residential factories and hotels, as long as the security guards are above 1.75, there will be fewer and fewer security guards over 35/165 m ~ 173 m in the future!
