Goodness, that is very long time, Chris!
But you finished before retiring age, didn't you?
Regarding your re-visit...I guess one should never go back....
Many years ago, I took my children to see where I was brought up, in Bolton.....
I was horrified, as I'm sure they were, too.
What had once been a lovely quiet, proudly preserved, residential area had become a run down shabby (weeds growing between the cobbles in the road) very tatty place.
No, never go back.....
