After using the toilet, do you wash your hands, or just wipe them? You've just demonstrated why washing toilets are superior. I cannot understand our misplaced, hollow pride in not adopting something which simply works better. I've even heard some especially crazy people try to say the japanese toilets are "perverted" - the hold tradition has on some people is just insane. Japanese toilets are simply better. For some…
Do you then pick up your chicken wings or pork ribs with your butt cheeks and stick them into your mouth, proceeding to lick off the excess sauce/grease?
I have just demonstrated why your example has a complete lack of logic or value.
FWIW, I use a baby wipe. This uses less water and about the same amount of paper. it actually does a little better job, is quicker and far more economical. My toilet will last 40 years with about 10% of the purchase and maintenance costs. I also carry wipes around to use in public restrooms so while you may get clean at home, I get clean on the road as well.
I mainly do this because I have itching/chapping issues if I don't.
