There are occasionally some whackos here too, buy I feel the US is another level.
The tram system in this city is only a few years old, so it doesn't have the stench. The trains are really comfortable though. Nothing like I have been on in sone places.
Do you ever wonder how sone seemingly normal people, don't shower enough?
I would imagine most people who dont shower enough, who aren't homeless, have some mental helath challenges of some sort. Depression I am sure plays a major role in it most likely. Then there are the real few who were never taught to properly care for themselves because their parents were twats. Then there are those that are just nasty and dont care.
