If I'd that one change I'd have gone to London Transport instead of EMI. Meaning I'd not be doing what I do where I do it and making a (good) difference to at least some people.

But... I might be an hexecertiff, I might be on humungous money with a final salary pension....
or I might have fried myself on the 600V rail.
Nil Desperandum. it's not over until it's over, and there's good stuff yet to come... just wait and see.
