 I say everything we're doing is preparing with smarts. We're doing studies on osteoporosis type things, muscle atrophy, immune system deficiencies and changes in our immune systems. Concepts, even our regenerative processes on Space Station are working towards systems that will be able to sustain and reuse air, water, urine, those type of things so we can continue and go long distances. So even the station itself is part of the process. Without doubt. Right now on the Space Station, Scott Kelly, another Navy pilot is up there and he's going to spend a whole year up there. He's, I guess, about two and a half, three months into an entire year in space. And the thing that I noticed towards the end of my six months is my body was still changing. My mind was still adapting. And I'll be interested to talk to Scott when he comes home to see if he ever felt like he had fully adapted in that one year in space. Because for me, I know at the end, I was still learning and still discovering new things. Yeah, current.
