That has surprised me. You have to work hard to be in it. I think one of the interesting things when I get back to Earth is going to be how I adapt back to that environment, which I'm really accustomed to, having been away from it for so long. I think just having free time. We have to make very productive use of our time up here, of course, because it's very expensive time.
Time is a very valuable resource in zero gravity in orbit.
So every day of our week is planned out in fairly minute detail. I always have something that I need to be doing. I think I'm looking forward to the point where I won't have anything to do. I won't have a lot of responsibilities, and I won't have a list of tasks for each day. I'll just be able to get up and be free to do whatever I want to do.
