    Frequently Asked Questions

    High heels trace their origins back to 10th-century Persia, where they served a strictly functional purpose rather than an aesthetic one. They were designed for horse riders to help them keep their feet firmly secured in their stirrups while riding. This historical use as a tool for cavalry preceded their transition into the world of fashion.

    Honey is a "perfect storm" of chemistry that prevents spoilage. It has an incredibly low moisture content and a naturally acidic pH, which creates a hostile environment for bacteria and microorganisms. Additionally, bees introduce an enzyme into the honey that produces hydrogen peroxide as a byproduct, acting as a natural preservative that allows the substance to stay edible for millennia.

    Sharks have been swimming in the Earth's oceans for approximately 400 million years. In contrast, the first trees did not evolve until about 350 million years ago. This means that for roughly 50 million years, the planet had sophisticated apex predators in the water while the land was still dominated by simpler vegetation like moss and rocks.

    In botany, a true berry must develop from a single flower with one ovary and contain its seeds on the inside. Under this scientific definition, bananas, grapes, eggplants, and kiwis are actually berries. The strawberry is considered a "botanical fraud" because it is an aggregate accessory fruit with its seeds on the outside, meaning it does not meet the technical requirements of the berry family.

    The human stomach contains gastric acid with a pH between 1.5 and 2.0, which is similar in strength to battery acid. To prevent this acid from dissolving the body from the inside out, the stomach produces a thick mucus lining as a shield. Because the acid is so aggressive, the body must completely replace this entire stomach lining every three to five days to stay ahead of the digestive process.
