As already written above, there are no completely healthy people. Even a newborn baby has some kind of pathology. However, if you are talking about people who have a good body, young looking, leading an active and healthy lifestyle, then there are more and more of them. Even in Russia.
There are no completely healthy people. Either you have something and you know about the disease, or the doctors did not fully check you.
For example, people are now being taken into the landing forces, so to speak, with the health category A. That is, there is nowhere healthier, but sooner or later, there will still be some sore.
