Public transportation is typically just in the real big cities here in the U.S. and is a pot luck of what you will experience. What I can tell you is that you better be on your toes because there are some whack-a-doodles that use it. As far as the smell you refer to, I can sympathize with that as well. I rode a bus once for a long period of time across country and I swear someone on that bus didn't know what a shower or deodarant was.
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.
I would agree. There seems to be quite a few of them here. I think it isn't necessarily health challenges for some, but rather some lack of social awareness too. Depression definitely here.
