COVID “Long- Haulers”

I dodged Covid until January of this year, luckily no side effects. My girlfriend has had it twice and has no taste or smell. My friend at work has been without taste or smell since February 2021. No doubt this is not a "natural" virus
That is so wierd!! I have never had COVID (as far as I know) but I've gotten both shots to protect my wife and family (just in case). I have a really good immune system and never get a cold or the flu. My wife will be sicker than a dog with the flu and I sleep with her every night and still don't get sick. I even share food with her when she is sick. She says that I'm an alien from another planet????
