Clean hands to lick thumbs + fingers!
It is 4 PM. you don't want to know where your hands have all been. maybe you'd better just wash them instead of thinking about it. what you should consider is what you wash them with. unless you use all our ecological, delicious smelling hand soap anyway, which is also free of triclosan. in that case you may give yourself a well-deserved and fragrant round of applause.
