This jetlag is irritating

In William Gibson's 2003 novel "Pattern Recognition", the central character has a theory that when one travels by air, one is moving faster than one's soul can keep up with, and jetlag is what you feel before your sould has returned.

And it is a strange feeling. People had told me before that jetlag coming back from the west coast of the US to Europe was particularly bad, and I now see what they mean. The time difference is 8 hours, and at the end of the journey you are at about the same latitude where you started - the journey thus having an unusually large time shift given the travel time. Plus there is the nasty fact that when it is 7am in London it is midnight in San Francisco, so you have to get up just when you are falling asleep.

And for me right now the situation is odd. I had a good holiday and I returned to London relaxed and invigorated. Normally when I am tired it is as much mental as physical, but at the moment I am not mentally tired at all - precisely the opposite in fact. I am raring to go. But my body refuses to go along with this, demanding sleep at odd times, which all leads to the weirdest of sensations.

In a day or two I shall be over it though.
