Reminds me a bit of how carrots became known for helping eyesight. (in short the military claimed carrots helped eyesight so they were feeding them to their anti-aircraft gunners, to hide their mastery of radar).
Carrots really do improve your eyesight though. Think about it. Who eats a lot of carrots? That's right. Bunnies. Now, did you ever see a bunny wearing glasses?
Except for Musky, but he actually doesn't sleep. I'm not sure what drug cocktail specifically he's on, but there's gotta be more than just ketamine in there.
