Transcript Excerpt

Starting point is 00:00:00 3, 2, 1, welcome. Starting point is 00:00:20 like, what, 95 days? Starting point is 00:01:07 longest in a row, basically. Starting point is 00:01:31 And your vestibular system is what's affected the most. Starting point is 00:01:51 It'd be like too arduous, you know? Starting point is 00:02:13 So I was about 3% low. Starting point is 00:02:32 that was kind of a first generation Starting point is 00:02:56 and the guys now that are working out on that thing Starting point is 00:03:15 I mean, that was still kind of in the early days. Starting point is 00:03:37 That's got to be so strange. Your body just wants to shrivel up when you're up there because Starting point is 00:04:08 It's like a fish in water. Starting point is 00:04:20 Every day. Starting point is 00:04:35 It's weird. Starting point is 00:05:02 I never even thought of that. So it just kind of floats off your body. Starting point is 00:05:22 We've shot so much video. Starting point is 00:05:45 So as you walk, as you go upstairs, that load that the bones feel, the compressive load, is telling the bone, hey, make some more. Starting point is 00:06:07 That 90 days has such, Starting point is 00:06:22 It's only a problem if you want to come home. Starting point is 00:06:39 It's like being air sick or sea sick. Starting point is 00:07:02 No, I heard it's a really good show. Starting point is 00:07:13 And they catch this terrorist guy Starting point is 00:07:30 If you went from Earth gravity to the space station Starting point is 00:07:56 if you're up there for a year and did nothing and you would also your all your muscles that Starting point is 00:08:20 There's nothing. Starting point is 00:08:51 So it's something that I never really noticed it, but I don't know how much of that is real and how much is like you're freaking out because you're in space, right? Starting point is 00:09:21 So right now, we have a lot of blood blood pulling up in our legs and our heart, Starting point is 00:...
