I'm in London, because I'm speaking about the teenage brain again at a thing tomorrow called the Youthwork Summit. This summit is run by some very enthusiastic Christians, which is a little bit worrying for me, as I'm a very enthusiastic atheist. The charming-sounding organiser knows this, because, obviously, I confessed, and he did seem to absolve me. So I think it will be all right, as long as no one tries to do what Billy Graham tried to do to me in 1981.
Anyway, this is entirely irrelevant. What is relevant is that I'm evangelical about the wonders of the teenage brain. I love love love the stuff I've learnt about the the neuroscience of adolescence in ten years of studying it. I did a talk on it last week to a mixed audience of young people and adults and I loved loved loved seeing the nodding heads among the adults and then loved times a hundred that it was a teenager who asked the first question.
It is without doubt my favourite topic.
But.
Tomorrow is a different one.
I will attempt, for the first time in the history of the universe, to explain scientifically the fascinating reasons for the horror that is the stereotypical (apologies) teenage bedroom. I will attempt to show, in a ten-minute TED talk, that the teenage bedroom is a metaphor for and an illustration of everything that's going on in their brains and lives, linking it to psychology, neuroscience and evolution.

I blame Simon Mayo. He invited me on his show a few weeks ago to talk about teenage bedrooms and explain them. My first thought was, a) I have no explanation and b) I don't care about teenage bedrooms. But it's amazing what the chance to be evangelical about my favourite topic on national radio can do to my brain. And within the half hour I was given in which to prepare, I had a theory.
And tomorrow, the theory gets its first full airing, complete with photos provided by
Photowitch, aka Helen Giles, who is still technically a teenager herself and therefore a very suitable illustration of the fact that teenagers are worth listening to and respecting and generally treating a whole load better than society often does.
