Hello there Robin, and welcome to the "crack"!
I am not a long way from retiring myself - will be out by July at the latest, but hopefully end of March. I had an allotment whilst I was working, and that was a big mistake; I had to give it up. Now I'm second on the list for another one, and that will be my retirement "working life". Best of luck matey, and let us all know how you get on.
