To much clean will kill you, because it will keep you from building enough resistance against germs, dirt, diseases etcetera.
You people with this cleaning phobia should visit countries like China or India for a change. You've never seen something like 10 Chinese men squatting above what looks like an open sewer, shitting, farting, laughing, reading a paper and talking loud with each other like it's nothing unusual. 
Thats so true...
I had a botany professor (yes, another college story) who was WAYYYYY WEIRDDDDD, he would actually eat out of the garbage can at parks because he said it kept his resistance to bacteria up. He was not poor, or homeless, just had this serious idea. If you were going to throw away drink or snacks in his class...he would actually finish it off right there in front of you. He ate anything after anybody! It was disgusting...but on a positive note, he had not been sick in over 15 years.
And the hand sanitizer is a BIG NO NO!!! It can actually make you sick after using it over a period of time. The bacteria that grows on your hands, and under the fingernails is normal to your body, and most will create an immunity towards it. But when using the hand sanitizer, it causes the bacteria to mutate to stay alive...thus, causing a stronger bacteria that will cause a lot more health problems.
