 I think there's that all that practicing. It's the reality of needing to be as safe as you can be. Spaceflight will never be safe, but we need to be as safe as we can. And that means you as a crew member being able to do your part. You know, if this happens, we need to do this. If there's a fire alarm, you need to, you know, don your mask and get to the main computer and, you know, and take the certain steps. And so we practice those things. We drill them. And we're also, of course, graded and watched and observed things.
