And one more example which blows my mind. During the Seven Year War, the British enlisted nearly 185,000 sailors, out of which 133,000 died. The main culprit? Yeah, scurvy. And even though throughout world history, there was overwhelming anecdotal evidence that citrus cured scurvy, science was not able to validate that fact until the turn of the 20th century, where literature became widely available and known throughout the world. And hence, no more sailing unless you have a big jar of lemon juice. Bang, bang, that was a fast one.
