what British culture is being lost and how?

The pub bore has become extinct. Everyone above a certain age remembers every pubs permanent fixture of the curmudgeonly old man stained and smelling of stale old beer.... Who'd corner you the moment your mate went to the bar to regale you with stories of how it all used to be fields round here and how he's seen it all as man and boy...

Also a lot less proper old tramps, not the new aggressive ones, the older English heritage ones who had their own language and would shake their fist ineffectively at the sky, whilst shouting strangely familiar but nonsensical words.
