I am in Beijing – and have managed to get through the day remarkably well considering I arrived late last night in a daze.

The daze was because I was trying an extremely ill-advised strategy of not sleeping during the 16 hours of flying so that I was tired enough to get to sleep at what my body would otherwise have been fairly convinced was lunchtime.

Even as I type it’s early evening in the UK, I’d just be winding up a day’s work at the office, but here it’s past midnight and barely a soul is stirring in the streets below. Actually I lie, there are horns tooting and even though I’m 11 floors up I can see a frankly concerning number of people wandering the pavements below. Maybe everyone’s body thinks it’s eight hours ago, could just be a China thing.

One of the upsides of not sleeping on the plane was that I managed to watch seven films while I was in transit. I wouldn’t have chosen to watch all of them if I wasn’t trapped in a tube hurtling through the air at many hundreds of miles an hour, but still.

Now, if you’ll excuse me I should try and get to sleep properly, I’ve got to be up early.
