I think it's funny that at my last rhuemy appointment we were talking about various things and got on the topic of jobs. I said that I don't think it would be a good idea for me to go back to teaching like I had been because of the general germiness of children and my rhuemy said something to the effect of "I don't think you're that fragile".
Well, flash forward to now where I just took a short trip with my parents that involved a 1 hour and 30 minute airplane flight where I came into contact with all of one person that had a cold over the entire trip and who came home sick? Me. So much for not being that fragile! I didn't even have direct contact with the sick person!
It was an interesting trip, though.
