This is a bit off topic but my husband was a preemie and never catches anything! When our sons were little I caught everything they got. Not my husband. He also never got the childhood diseases (measles etc, that all kids got back then.
I haven't had a cold since Covid started. The only thing I've had is some weird bug a couple of weeks ago but that's gone.
We're both thinking masks may be a thing we keep doing, especially during cold and flu season. So many people cough and sneeze w/o using any protection, let alone hand washing. Yuck! I don't trust other peoples' "habits" lol
