FWIW = for what it's worth
It's typically a lot easier to translate a sentence you know is true, simply because you can disregard huge amounts of information. For instance, if you're in the colours section and you see a sentence that starts with "swans are usually", you could probably fill in "white" without needing to think at all. But if you know that some sentences are meant to be tricky, you may expect other solutions such as "green" or "pink", which forces you to consider more alternatives.
Slicing onions stimulates the tear glands. Nasal/sinus congestion can affect the tears. Also, the basic components of tears are: Water. Electrolytes (sodium, potassium, chloride, bicarbonate, magnesium, and calcium). These are what give tears their salty taste. Proteins (lysozyme, lactoferrin, lipocalin, and IgA). The tears have only about one-tenth of the protein of the blood plasma. Lipids. Mucins. Thanks to kris650042 for this link: https://www.verywellhealth.com/what-are-tears-made-of-3421862
