I am an older guy, I don't do flu shots. But when I was young I worked in healthcare, was exposed to many nasty thing, so I am hoping my immune system is strong that a flu bug. Yes when we were deal with thing like patients with hepatitis, etc., we protected ourselves.
When we were young we got dirty, played out doors, played in mug, we were not constantly using hand sanitizer, we just were normal kids. Today it seem everyone is germaphobic. So I wonder how strong the younger generation is fight off common germs, because of being germaphobic parents?
