i used to catch colds very frequently. 6 years ago it suddenly stopped and i haven't caught one since. is it normal? . i'm 33. i used to work in a kindergarten and catch colds very easily (10-15 times a year). before that i used to catch 4-6 colds a year. it's been 6 years since my last cold. i was going through a period where my students were always sick. and then it stopped. moreover even if my wife (got married 4 years ago) gets sick quite often i never get her colds. ever. i find it really weird that whatever i do i don't catch colds anymore. am i just lucky or is there something more?
