Honey never expires

Archaeologists have found 3,000-year-old honey in Egyptian tombs that was still perfectly edible. Honey's low moisture content and acidic pH create an environment hostile to bacteria and microorganisms, making it essentially immortal.

Octopuses have three hearts

Two hearts pump blood to the gills, while the third pumps it to the rest of the body. When an octopus swims, the heart that delivers blood to the body actually stops beating, which is why they prefer crawling — it's less exhausting!

The Feynman Technique for learning anything

Richard Feynman's method: (1) Choose a concept, (2) Explain it as if teaching a child, (3) Identify gaps in your explanation, (4) Review and simplify. If you can't explain it simply, you don't understand it well enough. Changed how I study.
