And how many times do people go upstairs (or to the photocopier) and spot an interesting problem and return only to realise they didn't do what they set out to?

OK it happened to me as a teenager - but not nearly as often.

The thing, Billy, about discussing the effects of aging is that others have been there before and solved the problems. We learn. And abrupt comments strike home faster - reply in kind if you want but don't get sucked into being goaded by a flamer - and I don't mean Clinton (reallllllllllllllllllly).

The only problem is remembering the solution. I make lists now. I speak to myself repetitively when going upstairs, and come down with a new song but not what I went for.

As Roy Bailey says when out with a date (these days) "Is this place yours or mine?"
