Well, I'm learning all about medicine right now. I used to do astronomy stuff, like... making rockets and things. Star charts. But I don't want to do that anymore... I like taking pictures sometimes. And drawing. And when I was a kid I used to make buildings, but then I got bored of that... [This has all been very matter-of-fact, but then he brightens.] And I've been learning a lot about the Fleet, too.
