I hope I am not tempting fate by saying this ---- I have been cold free for over 3years and last had flu over 2 years ago.
I think it is due my winter hibernation practice. I live alone and have all my supplies delivered. I do venture into public places about once a fortnight in winter on average, so I am not exposing myself to all your germs
It suits me (
because I like me )-- I am quite content with my own company. Hermit ?--- Recluse? --- maybe --- I call it Peaceful
