and put each inside a small bowl.
dunk each hand in the bowel.
now someone else cleans your left hand with paper by and your right hand with water - both as thoroughly as possible.
now, two questions: which hand is still dirty and stinks? which hand would you pause if you had to lick it.
it really is as simple as that. our paradigm is just wrong.
a good middleway is to use wet toilette paper! enjoy superior cleanliness!
