I personally think you're just a misery John and probably because your life is at the point where you have little to occupy you generally, you find pleasure in being disruptive as you're jealous of others having a life. Harsh to even type that, but i can think of no other reason really.
You live nearby in a reasonably nice part of london with plenty of green space near you and good local bits and bobs for the retired to get involved in - to seemingly get off on winding people up on here is ridiculous.
As others have said before, someone of your age should be an asset to the forum, not a hinderance.
