However, had you read that spot of text, your spider-sense should be immediately shouting: “DANGER! DANGER! The sun is out and you’re inside playing a Tetris clone! Loser!” But, after you’ve psychologically beaten that PSA to death with denial and self-loathing, it would shout: “Wait, no gravity and that’s the least of my worries…hooo boy, this is gonna be bad.”
I was you’d be right.
