I grew up in Leeds and Googled one of the estates I lived in, and it has all been demolished.
It was a shit hole in fairness, but it saddened me to think I have some memories of being in that house and it is no more.
I lived in Bradford, it only just hit me the last time i went back, that my middle school and upper school have been demolished. Also quite a few of the pubs i went to have been demolished or now a take away or kindergarten. Even some of the woods, open ground I played on have gone. Only 42, and me childhood as been wiped out but in memory
