I have two friends who got Covid Pneumonia.
They both got it within days of each other. Tom smoked a pack a day, Bob never did.
I went to Tom's funeral at the end of May. Bob spent a couple of months in rehab.
Doctor told Bob if he'd smoked, he wouldn't have made it. Stuff is bad news, do what you're told to do.
Sorry for the Loss of Your Friend, Gun.... that sucks Yessir, the Complications can be Crap. On the good news I got a real good sense of smell cuz I can't smoke a damn thing and I don't want to!
