Before aspirin was introduced, people would chew on the bark of the white willow tree to reduce fever and inflammation. White willow contains salicin, a chemical similar to acetylsalicylic acid found in today’s aspirin. In fact, in the early 1800s salicin was used to make Aspirin. The tree has anti-inflammatory effects and although it may be slower acting, the effects of salicin in white willow are longer lasting than Aspirin. Of course, ingesting this bark also has the negative side effect of giving you a very upset stomach. 2. The human eye can detect somewhere between 100K-10 million shades of color. For reference, HDMI 1.3 supports 30 bits or 1 billion colors, 36 bits or 68 billion colors, and 48 bits or 281 trillion colors. (QF 454) 3. One of the common early uses of Heroin, which was marketed as non-addictive, was to help treat people who were addicted to morphine, even though Heroin ultimately proved to be more addictive. When morphine was first isolated from opium in 1805, one of its early uses was a “non-addictive” drug to treat people who were addicted to the less addictive opium. (QF: 475) 4.

Further, if you eat TNT, your pee will turn red and look like blood, though it is not. In fact, during WWI, munitions workers who handled TNT were called “canary girls” or “canaries” because their skin that was exposed to the TNT turned the aforementioned colors. On the more serious side, prolonged exposure to TNT causes liver, blood, spleen, and immune system problems among others. 5. Human sperm cells on average tend to be able to travel about 7 to 8 inches per hour (about 17-20 cm/hr). (Fact 502) 6. The reason you can see eye floaters better when looking at, for instance, a bright blue sky, is because your pupils contract to a very small size, thus reducing the aperture, which in turn makes floaters more apparent and focused. 7. Humans enjoy five or more different tastes namely: sour, bitter, salty, umami (associated with meat), and sweet. We can taste sweet things thanks to two proteins generated by two separate genes. Cats, on the other hand, have a mutant chemoreceptor in their taste buds that prevents them from tasting sweet things, which is actually a trait shared by all cats big and small, not just domestic ones. 8. Another word for growling “tummy” sounds is “borborygmi”. (Fa
