I've had lots of close calls. My nephew and his wife were over visiting last year, I sat right next to them in my camper chatting for 30 minutes. 4 days later, they were both in the hospital with it. Most of the people in my office had it, my son had it. On Easter this year, we were over at my sister in laws, spent the day in their house, ate together, shook hands with him, hugged her, 2 days later they were sick with it.
Either I'm lucky, strong, or the shots are working. Very sadly, I know a few who have died from it.

DM, hang in there, get well!
