There are a suspiciously large amount of semi-naked men walking around Cairo airport as I am on my way to Nairobi. They are clad only in sparkling towels and shawls.

Obviously, it’s time for the Haj – the revered pilgrimage to Mecca that should be undertaken by Muslims at least once in the lifetime.

The surly customs guards have melted, wordlessly pushing them through the customs queues while we look on.

Otherwise, there are plenty of people pulling down their swine-flu face masks to drag on a last cigarette before they board their late-night flights to Kenya, Ethiopia and Saudi Arabia.
