I am very tired and unhealthily full of coffee in a cheapskate-business-taveller's hotel near Shinagawa. This fact is currently going to waste, since I'm suffering from Friday lethargy. Hmmmm... maybe I should press myself to go to Shibuya and look at the other 12M people there.
As an aside, I reckon that this return trip is going to use roughly four tonnes of jet fuel to transport my useless self (and the required portion of Mr Branson's plane) back and forth. Christ! We need more fibre cables.
