Well, I've survived Avionics up till now, and I'm coming into my sixties, but it's never too late to change course. I don't know how old you are or where you live, but why don't you investigate the University of the Third Age - a wonderful organization of people like us who have years of experience in all sorts of fields and who contribute their knowledge and skills to other folk as a hobby-cum-job. I must admit I still love the buzz, but if you are feeling jaded, why not try for an ex-pat posting, that is a whole new ball game. Anyway best of luck in whatever you do.
By the way, Blacksheep, have we ever had a drink together? Does Lanark mean anything to you? If so, I tried to call you to say hi and was told you were on leave.
