When I was in my early teens - in the days before frozen chips and frequent take aways - the food that could nag at me to leave the house at very short notice, just because I needed it NOW, was chips!
When I was in my later teens at university the addictive nagging to leave the flat would come from alcohol!
When I was in my twenties, and thirties for that matter, the call came from chocolate - no matter how late nor far away the shop might be (the benefits of car ownership).
When in my forties I don't recall anything that called me - the inertia possibly greater than the addiction to any food.
I laughed yesterday when, now in my fifties, I left my cosy home and went out into the rain just to buy a pomegranate.
How our priorities change.
