How astronauts deal with the boring parts of being in space
Is there training at NASA or elsewhere for this kind of stuff? There are analogues of the space station and the modules to prepare you for how to handle things. You go see how you're going to do the so-called mundane things you'll be doing in space.

But we never really take weightlessness training to do other things, like cleaning your teeth.
