Sorry! Didnt mean to offend! Indians typically use their hands to wipe their butts with water. I think it is cleaner and uses less water relatively. The joke I intended to make was that India has been using water to wash themselves for several years whereas the west needed the invention of a bidet to force the change.
I agree! But also both Hinduism and Islam had cleanliness rituals baked into their religion. Maybe they were able to notice historically that periodic bathing multiple times a day, helped them to avoid diseases!
