Age getting the better of you, eh, Ed, and affecting your memory!
yeah, i often walk with a stick for my back and my balance. although i often just use one of my shepherds crooks so i can claim it's for catching sheep

memory, selective now days. i could tell you how many of what breed and what sex sheep there are in each field and how many are lame in each field and which ones have had fly strike this year etc. i could tell you what sort of engine and how big it is and tell you all about the gearbox in quite a few tractors
yet i have to think for a couple seconds about my age
now days half the reason i ride is to keep me active and fit (like i don't do that at work every day anyway!

), i think that's something that suggests your getting on a bit?
Cheers Ed
