A little while ago, I was talking to my mother and the subject of early computer games came up. (I don't remember why.) I said something about not being able to remember the earliest computer games, and she said neither did she, since she was too old for such things when they were first developed.
I am the same age now as my mother was when I was born. When the earliest computer games were available, she was younger than I am now. I still enjoy playing computer games; although I don't spend very much time doing so at the moment, because I'm too busy, I don't envisage that I'll ever go off the idea altogether. (Here's one I particularly like. It took me ages to work out what you have to do, though.)
Yet the concept that adults don't play computer games doesn't seem particularly alien. And it does seem to me that people of our generation are much less "grown up" than our parents' generation at the same age. Most of my friends don't have kids; only a few are married or settled down in a particular location, and not all of them have fixed on a career yet. We read fantasy and watch Doctor Who and play World of Warcraft (well, I don't, but I know people who do) and it probably all looks rather childish from the point of view of Real Grown-ups.
Maybe I'm biased because a lot of the people I know are academics or postgraduate students; I can certainly think of exceptions to what I've just said. But it does seem to me that there has been a slant towards not letting go of your youth, or even childhood. When my mother got her first teaching job, she cut her hair so as to look grownup and responsible. I used to think I would cut mine (it's long) when I was 30, but now... that's not as far-off as I'd expect.
I suppose that in many ways the eternal-youth thing is superficial. We might look scruffy and read books about dragons and listen to new music, but we still have grownup responsibilities. I mean, there are good reasons why J and I don't have children yet, even though we might like to, and not all of those are under our control.
Whither our generation, though? Will we still be wearing T-shirts with obscure slogans and playing computer games when we're in our fifties? Or will things take another turn? I would hesitate to make any predictions.
