Proper use of Paper Towels!

According to Joe Smith, who in this TED talk here argues that, 571 million pounds of paper towels can be saved if only Americans use a simple logic of 'shaking their hands 12 times' after washing their hands and 'folding the paper towel' once to dry their hands. That would be out of the 13 billion pounds of paper towels consumed every year in the US.

This aspect makes me wonder about the obsession with cleanliness which had gone to such an extent that ordinary mud in the earth is referred as 'dirt'.

Some more food for thought!
