What a flamatory question... I live and grew up in a caucasus country.... I also frequent Asia.... Unhygienic people aren't exclusive to Asia, as I have witnessed throughout my life. Seriously, the only difference that cloud one's brain about other countries hygiene really is the architecture, planning and surroundings. We assume that other country's people are more hygenic than others simply because the places they inhibit are better organised and cleaner. That is really not the case. The west is just as bad regarding bathroom hygiene.
I've worked with many many people who don't wash their hands at all! And they call me OCD for washing mine! Ha! WTF!?
