Some years I don't get a cold anyway, but "can confirm" I haven't had a cold or cough this year or last.
I have not had a cold or Flu for several years. I have the Flu vaccine every year and have done so for years. There is a strict rule at our home, if you are sick or been near sick folk don't visit and this has been in place for years. We have sanitiser at the door and have done so way prior Covid 19.
If you have young children that is not possible. Their friends are always sick. There is about a 100% chance that one of their friends are sick at any one time and a 99% chance their parents won't keep them at home, rather they will partake in every activity they are scheduled for. Something about what doesn't kill you makes you stronger. Hear it every day.
