I once heard that the British and the Chinese were the filthiest nations in the world for toilet clenliness in that the former wipe away as much faeces as they can using tissue paper, smearing it against the nipsy and removing most but not all of the waste, whereas the Chinese simply drop their trousers, push it out and pull their trousers back up again.
Having spent six years spraying my backside clean as a whistle and half the time giving myself an enema in the process, and living with a woman who does it using soap or Lactacyd then the idea of going back to wiping my bum seems rather revolting.
If you vomit do you wash your face and gargle with Listerine after or do you simply wipe your mouth on your sleeve and be done with it until your next bath/shower?
Dirty bastards we once were.
