Do some people gain high immunity genetically?
I've seen many people who live in the same environmental conditions as that of mine but they never got infected by cold. For example my father would get cold only one or two times a year but I get infected by cold nearly every month. Not only this there is an old friend of mine whom I've never seen sick. When we were young he always asked me why do you get sick so often whereas he would never be sick.
