I have a cold. A nasty siffling, sneezing, coughing, aching, stuff head, and fever kind. The kind where you can't sleep because you can't breathe.
I think I got it from shaking people's hands. People's hands are dirty. The average American does not wash their hands at all, and most of those who do don't wash their hands properly. The #1 cause for spreading of germs is through hand to hand contact. People do not wash their hands!
I like the Church we've been going to, but they do this extended passing of the peace which is nice, but I feel a little put off because I don't like touching people and don't like having people touching me. So I take my hand sanatizer and clean myself afterwards. Some people give me strange looks, but I say to them; "If you washed your hands, I wouldn't have to do this!"
