Yeah, that was a bit depressing. The PFAS make it a lot more water soluble. My guess is that old TP didn’t break down very well at all, and was kinda splintery (or at least more paper-y).
Luckily, the bidet removes much of that as long as you don’t use TP. And for those that have bad pipes or a septic system, I think a bidet is an invaluable part of saving you lots of money, since you aren’t packing extra material down the pipes.
You wash your ass every time you take a shit, even when at work? :P
