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!
Honestly humans are stupid and it is so interesting what we learned to do for sometimes awful reasons that turned out to be pretty good for us. I mean a lot of medicine was "getting the devil out of you" for a long time and it sometimes happened to work because people would just do random shit.
