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. So you better go take that test or write that essay before you forget everything that I said. I recommend washing down that fast meal of learning with a big glass of OJ. And once again, thanks for tuning in for another Hip Hughes video.
