Rise in people discovered dead and decomposed in UK raises concerns

Living in the UK, I only started to interact with my neighbours once we bought our house.

While renting, I was always surrounded by other people renting. People were more transient and the properties lacked gardens to promote to being outside long enough to see any neighbour.

In our last rental property, our upstairs neighbour changed five times in about 15 months. We gave up knowing who was who by the end.

In Finland, it is considered so either awkward or a faux pas to be out in the hallway of a block of flats at the same time as a neighbor, that people develop a habit of looking out the peephole before opening the door of their flat and stepping out. (A HN poster from Sweden said the same of his own country just the other day.) I think you would run up against immense social resistance to urban-dwellers having to get to know their neighbors, not because of "paranoia" but simple desire to keep to oneself. There has got to be another way for social services to check in and be alerted.
