My routine used to be as follows. When I was young we divided people into owls and larks. Owls stayed at the lab till midnight because that's when it seemed young molecular biologists would like to work. And they then went home and came in the next morning at 10 or 11 o'clock. Seymour Benzer was an owl. He always worked till… almost right through the night. But then he slept all day. I was both an owl and a lark. That is, I liked to work late at the lab and then come home, and then quite often go in early: 6 o'clock, 5 o'clock. But as I grew older I had to choose, so these days I'm much more a lark, that is, I like to get up very early in the morning, when the whole world is asleep, 4.30, 5.00am, and then I can read, I can work on my computer, I can scribble my little pieces of paper, and I can also do quite a lot of daydreaming there. And then I used to do my experiments in the lab at that time as well, because then by the time everything came in and all the secretaries and then the usual mess of one's life started, I'd already finished my day's work, so I could just relax then and do all this, the rubbish I had to do. So I think that's important, and nowadays of course one has powerbooks and computers that one can carry around with one, and of course I have this, I have a big database in it, and so I spend quite a lot of time doing research as I travel, and in hotel rooms and at home I have my computer and that's all one needs these days.
