Well that was a ridiculous rabbit-hole to go down.

My main thought since they first announced this trip was, what are they going to do for 3 entire days? That's a lot of time for people who haven't been trained up the way astronauts have to potentially experience some extreme mental states.

Being stuck in a tiny, tiny space with strangers and absolutely no way out seems like it could potentially cause issues even for people who have been psychologically screened. Hopefully these "experiments" they're supposed to be running will help keep them occupied & distracted.

"Trapped alone in a small room with no way out", sounds like a few experiences I've had while travelling since January 2020. Elon, if you're reading, I'm happy to volunteer myself for the next mission.

For a long flight, I make sure to take a freshly stocked ebook reader. They are light and have great battery life.

Reading in space seems like missing the point of the "once in a lifetime" trip though. They probably have "fun activities" planned.

I understand they will also be performing some science experiments. Also for this maiden flight, I bet they get plenty of attention from earth too.

Holding poop in for 3 days is not unheard of, let me tell you.

There's a toilet on the ceiling and they're packing a bit of fresh food that they'll eat first. After that it's "space food".
