@ebrown p,
If you read what I wrote, I said that any health care professional will tell you doorknobs, handles, etc carry a lot of germs that live for quite a long time.
I also said that the human body is strong, and we naturally resist everyday stressors....but not when a new stressor is put in the environment.
If you want scientific evidence, call your doctor, or use google.
yes, you can catch something from a doorknob.
These aren't rituals, they are sound, tested methods of hygiene, which I wouldn't expect a 4 year old to understand.
I am however, surprised an adult is arguing the point that keeping your hands, after you just cleaned them, off an object that someone with unclean hands just touched.
Why is it you think you wash your hands ebrown? It's because you've been touching items that have been contaminated, and not just your penis either.
What? You understand that putting your hand in a bucket of piss would make your hands unclean, but touching a doorknob that has someone elses ****, saliva or urine on it is ok? Just because there's not enough of it for you to see, doesn't mean it's not there, including things you don't see with the naked eye, like viruses.
I'm being serious...go to the nearest public restroom, and link the doorknobs.
What's the difference between doing that and reaching up and touching your mouth with the same hand that opened that door knob?
past this you're just baiting ebrown, you obviously know that this is not some theory.
