Tried to fob me off with that 13 years ago as well!
Anyway. Back to the present (or the very near past to be precise).
Been for my hearing test today. Fan-bloody-tastic. What a palaver just to get told what you already know.
I've a theory - the human body only has so much power, energy, essence, mojo... call it what you will. The more you channel that into running the less there is for other parts. Maybe these good times and PBs I've been getting are taking their toll. More power in the legs = advanced decrepitude elsewhere ??
