I came back from 22 hours of business trip. I would rather not have gone, but I seem mostly unharmed. We'll see whether I get sick, I seem to have some kind of upper respiratory infection. The air in the trains is horrible for some reason, even with no smoking. Anyway, I guess it was useful. I only got limited sleep on the train, so I was near falling asleep during the meeting some times. And of course my special field only came up a few minutes before I had to run for the train. The meeting should have been over by then, but you know meetings.
