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?
Carrots contain beta-carotene, which can be converted into vitamin A in the body, which is important for eye health. While they won't give you superhuman vision, carrots do in fact support eye health.
Which also honestly makes the analogy better now that I think of it. Just as the grain of truth behind the carrot rumor helped sell it. Hard work and determination can in fact help you make more money. But of course just as an improvement in diet isn't likely a huge factor in detecting planes flying at night and perfectly pinpoint artillary at them. It's obviously not the difference between the people working 2 jobs to pull in sub 50k/yr anually and the people purchasing Yachts big enough to hold smaller Yachts.
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.
