Pardon me if this seems like bragging or such like but I haven't had a cold, sore throat or even a headache for over 30 years. People say 'oh you shouldn't say that, you'll get one now' but I don't. DH hasn't had a cold for about the same time either. Now believe me, he has had lots of other things, including diabetes and cancer so he has had his fare share. I have often wondered why we don't get colds. I had one after the other as a child and have even wondered if I have become immune in some way, although I know this is unlikely. Apologies if this is irritating for those of you who are suffering at the moment!
