Good question...I also would like to know the answer. I have been to numerous Asian countries where they don't use toilet paper....even in private homes. If you're lucky there will be a bucket of water to wash your a***s!
If you are not lucky...there will be nothing! Many public toilets have no water and no toilet paper...they have long given up on paper because some tight a**s will steal it! I have had my share of disasters!
Typically, many cultures wipe (with toilet paper or leaves -- hopefully not poison ivy) with their left hand or hold their "noodle" with the aforementioned hand.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
