I suspect that a monogamous sexual relationship would be much more pleasant that picking one's nose and eating the boogers.
I always remember that God said, "It is not good for man to be alone." That quote didn't come from a secular psychologist, Playboy magazine, or a lukewarm, backslid, social gospel preaching pastor. I don't know whether the study was conducted well or whether the researchers simply had another agenda. I do lean towards the belief that most people are intended to have partners. If that belief is true, then I can believe that most people are going to be healthier in that marriage relationship than they would be either being celibate or having multiple partners. Of course, one must still exercise wisdom in choosing a partner and choosing the time to enter that relationship. I believe that my immune system would have been stronger if I had found the right person.
I don't know whether my nephew gave me a cold. He was fighting something when I visited, but my dad caught something as well. I've heard people talk about their children bringing home all kinds of things.
Actually, the bathroom thing shouldn't be all that connected to colds. The germs that cause respiratory infections have nothing to do with going to the bathroom. I'm pretty picky about washing my hands, but when I do, I'm worried about a different set of germs.
It's funny, but I use hand sanitizer a great deal when dealing with my reptiles. When all is said and done, there's very little that I can catch from them. Humans and reptiles don't respond to the same bacteria or viruses, so they can't pass much to me. I should worry more about hand sanitization when dealing with other people.
I've heard that most respiratory bugs actually enter our bodies through our ears. The article that made that claim suggested dripping a little hydrogen peroxide into the ears every day during the cold and flu season.

Colds aren't the only thing contagious. I attended a house party, and went to the bathroom. When I lifted the seat, it was obvious that someone in the house had (as my Mother used to call it) "the dire rear." Washing didn't help. I wound up in the hospital for five days due to dehydration.
