just water vs. soap and water
does anyone know of any studies about the effectiveness of washing one's hands with only water vs. soap and water? my wife has dry skin and hates soap, and my experience in the army is that soap is overrated considering how long infantrymen are out in the field without cleaning themselves (of course everyone in the army gets all sorts of shots for who-knows-what...). you don't really want to wash your hands with your limited drinking water when it's 40 degrees, and i got made fun of when i once pulled out some hand sanitizer. go figure...
