Among the fragments of school history left in my brain is the phenomenon of St Vitus's Dance. At various times during the Middle Ages, groups of people succumbed to what is now called choreomania - the overwhelming desire to dance. By all accounts, the craze is best explained as a physiological response to hardship, bound up with the different religious and superstitious assumptions of days gone by. In other words, it could never happen again.
And yet it has. A visitor to earth studying television schedules would almost certainly conclude that dancing was the single most important human activity. There's Strictly Come Dancing and Dancing on Ice. Meanwhile, the BBC has made a show where members of the public compete to be Britain's best dancer, while on Sky 1 other members of the public compete to be, er, Britain's best dancer.
The nation is in the grip of the most widespread and inexplicable dancing mania in at least 400 years. For a confirmed non-dancer like myself, this is all very alarming. Don't get me wrong, it's not a case of snobbery towards reality TV: I'm as fond as anyone of a minor-celebrities-trying-to-become-actual-celebrities showdown. (I owed my own appearance on Mastermind to an unusually generous interpretation of the word "celebrity".) But the seriousness of it all is peculiar and alarming. The judges glower at the dancers as if they were a jury asked to weigh up a murder case. They deliver crushing verdicts: "You don't have any Latin flair at all"; "Your hands are all over the place."
At what point did dancing earn the right to be presented as a matter of such importance? And how come I missed the meeting?
That's the crux of the matter for me: self-preservation. To put it politely, I can't dance - and not in the sneaky, disingenuous, suddenly-realised-I'm-quite-good-at-this way of the people who appear on Strictly Come Dancing. I mean I literally can't, and won't, dance. The few bits of dancing I've ever attempted have been so bad that my wife has prohibited me from ever trying it again.
There is no place for me in the dance-oriented new world order. In the coming survival of the funkiest, I'll be picked off straight away, no doubt with an uptight lady making disparaging remarks about my foxtrot.
So this is a plea for sense. Let's demote dancing from the position it's managed to occupy, back to the "very occasionally and only when drunk" box where it belongs (along with other regrettable, alcohol-fuelled habits such as kebab-eating and making unsubstantiated claims of sexual prowess). If we carry on like this, it'll be the 16th century all over again. You know what they say: those who do not learn from history are destined to do the paso doble. I can't issue a direr warning than that.
