I wonder what else was imported from NK? I’m sure the NK people are immune to a lot of stuff they are carrying around in their bodies.
It’s like when we go to Taiwan. We have to be careful what we eat and drink. The natives have built up a tolerance to whatever and don’t get sick by drinking the water etc.
Very good point. After my stem cell transplant, although us patients were in a sterile environment, (complete with 2 doors into to the unit and a suction mechanism to keep the hospital air from the unit) urged us to shower daily because our own skin carried bacteria which could make us sick since we had zero immune system. (It wasnt easy to do that on several days!)
