Wash Your Hands!

I was watching the Today Show this morning, and they had a doctor on talking about germs. He made several significant points:
Soap does not kill germs, it washes them away. Because of this, spending the time to wash properly is key. He went on to say that getting water to a comfortable temperature is important in getting people to wash long enough. They are now teaching kids to sing the alphabet song while they wash (my son shared this with me about a year ago).
We should wash before meals, after using the toilet, as we come indoors, and at any time we feel we have come in contact with contaminants. I hope I don't need to explain the first two reasons. The third is based on the fact that we come in contact with contaminants in less controlled environments. The final one is that after we shake hands with someone who has a cold, or have touched something "dirty," we should remove as many of those germs as quickly as we can.
One thing that surprised me was his recommendation that we use liquid soap rather than bar. His reasoning is that germs can be on the soap, so while we may contact a germy pump head, it is in very limited (and dry) contact with us.
