Pizzas galore!

There is also a Darwinian component to this. Scientists have measured, for example, how male fertility varies with distance from one's habitual partner. And guess what? According to a report in the journal Personality and Individual Differences, a man's sperm count doubles when he spends a lot of time on the road - up from 389 million sperm per ejaculate to 712 million. Which, I am sure you will agree, is a lot of extra sperm.

I suggest that it is the coming together (if you will forgive the expression) of these factors that creates such an explosive sexual cocktail within the security-controlled perimeter of the Olympic village. Not that this is a bad thing. I have always regarded sexual promiscuity - for a single person at least - as a basic human right, even if it is no panacea for happiness or, indeed, anything else. Of course, many athletes will abstain, others may even disapprove. Only one thing is certain: they will never again enter a place quite like the Olympic village. Not, at least, until London 2012.
