Pretty similar here in Thailand (and Japan too) in the rural areas, Luca. The difference is that the Thais / Japanese do manage to keep them clean. They also have this great "bum squirter" thing by toilets (both squat and western).
On a recent business trip to Singapore I felt unclean all day because I went to the loo (a lovely clean Singaporean western style loo) to take a dump, and could not do anything but wipe my ass with paper.. I wanted to go back to my hotel and take a shower afterwards..
If I ever do leave Thailand as my main home base then I will be taking a bag load of those 'bum squirters' and forcing my entire range of family and friends to install them in their houses!
On a lighter note, when you see what the Chinese are willing to put in their mouths and eat, I am suprised they are so prudish about where they stick their buts!
