AMEN brotha!
WASH WASH WASH, every chance that you get, wash your hands! That is simplest way of preventing the spread of germs. Can't wash? Hand sanitizers, albeit harsh for you hands if they are chapped, are a good "Bandaide" until you can wash your hands. Dry Chapped hands? There are great antibacterial lotions out there.

I am almost obsessive/compulsive about washing hands, espcially after doing some experiments in Micro-Biology! In the college that i was at for this class, the toilets, and their handles, had fewer types and counts of bacteria than our computers' keyboards!

I am one of those that adhere to proper hand washing techniques everytime.
