It will be my birthday on Tuesday. Last year, I reached the painful conclusion that there wasn't enough time left to read every book ever written. This year, my gloomy realisation is even more painful - I will not be able to correct everyone's mistakes before I depart.

You know what I wonder about? This - the more details of Sven-Göran Eriksson's love life that appear in the press, the more contempt he attracts for his choice of substitutes in England games. Now, we haven't done the research, but my guess is that Sven's performances in the sack and that of his subs on the pitch are not correlated. So why do we link them?

Iain Dowie famously coined the phrase 'bouncebackability' to describe Crystal Palace's ability to come from behind. But this is a typical manager's idea, so optimistic. What fans are interested in is 'throwawayability': which teams toss away hard-earned leads? Now we know that 'throwawayability' exists because we proved last season that 'bouncebackability' exists (although, hilariously, Palace don't have it) and 'throw-awayability' is the flip side of it.

Last year, the journalist Malcolm Gladwell conducted a survey of chief executive officers of Fortune 500 companies for his book Blink. He discovered that while in the US population 14.5 per cent of all men are 6ft (1.83m) or taller, among CEOs of Fortune 500 companies the proportion is 58 per cent. And while 3.9 per cent of American adults are 6ft 2in or taller, almost a third of the CEOs were that tall.
