The profession of courier has not appeared for a long time, that is, 10 years. It is said to be the longest-lived profession, so I'm afraid it's difficult to draw a conclusion. In contrast, the postman can judge whether you live long, but you can't see anything special about it.

There is no point in saying this, because the express delivery profession often exercises during the express delivery process. Then the average life expectancy of athletes is no different from that of ordinary people.

But I have to admit that regular exercise can really exercise and enhance immunity, so the professional characteristics of couriers are not only regular exercise, but also greater freedom, which can really make people healthier.
