I began playing football - about which I was obsessed (the first in a series of obsessions, if I'm honest) - when I was 9. I was a bit crap, though you don't admit that to yourself as a child, and I dreamed of playing for my favourite club and for England. If someone had told me I could 'change sex', I have no doubt I'd have said "Oh, yeah!"
Fast forward to age 14 and the next obsession (a popular beat combo) kicked in with a vengeance. I fancied the pants off one of the blokes in the group - all thoughts of being a bloke long vanished.
Kids, eh? Getting mad, unfeasible ideas in their heads for thousands of years. Only now, some adults - including the ones with most responsibility for protecting them - are encouraging them to do some particularly drastic things to themselves as a result.
