Country roads take me home

So, the move to the country looms. It was Mrs Spuggy's idea, she is in charge of important decisions like moving house and new human beings; leaving the "red or white wine" decisions to me. She was brought up in the county and so is able to identify different flora and forna. I on the other hand, am a died-in-the-wool townie and wouldn't know a crested grebe from a cheese and pickle sandwich. Having ruminated about this I decided that I had picked up at least one discernable skill in my townie upbringing: identifying makes of cigarettes.

I typed the following off the top of my head:

Lambert & Butler, Malboro, Malboro lights, Silk Cut, Embassy No 1, Embassy No 6, Embassy Regal, Capstan Full Stength, Moores, John Player Special, John Player Reds and Blues, Winston, Peter Styvessant, Dunhill, Superkings, Sobrani Russian, Sobrani Cocktail, Golden Virginia, Old Holborn, Lucky Strikes umm and those horrible menthol ones.

Just like birdwatching, I reckon I could stand quite a way back from the shop counter and still name most of them. The strange thing is I am not really a smoker. I occasionally cadge one of Billy-Bobs but havn't really smoked since my twenties. All the above cigarette identifying skill was picked up in my teens. Why is it then that I can't remember any chemistry?
