I learned that there’s no way I could handle a mission to Mars.
I learned that the Mars mission will fail because you’d need a 500 Tb drive for the porn collection, too much dedicated storage for lube, and by the time the crew reaches Mars, they’d be unable to reproduce because they’ve wore down their willies after the lube ran out.
I found there’s not enough interesting material on YouTube to fill the time I’m doing nothing from work.
