The neighborhood I moved into isn't exactly pretty nor clean, but overall liveable. Then, I am continuously annoyed at littering, finding puke on the pavement in front of the appartment building I live in, people can be loud, etc. Thing is, I remember the area from visiting when I was a kid (like 30 years ago) and it was in a worse state back then. Recently in the just-for-fun soccer practice team I met a guy probably in his mid-60ies who - after practice when we hang around - told a story from his childhood growing up next to the red light district. I asked where that was, and he grew up 200m away from the place where I live, same street. The town I grew up in was just generally gray. Now its painted, has pedestrian zones, etc. When looking for an appartment a landlord showed me the storage area of an apartment in the basement, this storage area, he told me, had been in the past rented out to labourers, as in bunk-beds for 6 men. I asked him when it was and it turned out that this was during my lifetime (not turn of the 18th to 19th century or something, more like "the 80ies").
