Ivan mentioned in a post that he has observed that many PWP's never seem to get a severe cold or the flu. That really struck me because I never (since PD) seem to get anything more than the sniffles. (knock on wood) I haven't had the flu in ages. Of course I get an annual flu shot, but that isn't a guarantee against becoming infected. What seems just as bizarre is that when a family member gets the flu or something similar I never seem to catch it. It makes its way through everybody and leaves me alone. What's up? Any thoughts?
