Leprosy is not auto-degenerative as commonly supposed, meaning that it will not (on its own) cause body parts to be damaged or fall off. Leprosy causes rashes to form and may degrade cartilage and, if untreated, inflame tissue. In addition, leprosy is only mildly contagious, partly because 95% of those infected with the mycobacteria that causes leprosy do not develop the disease. Tzaraath, a Biblical disease that disfigures the skin is often identified as leprosy, and may be the source of many myths about the disease. #learnStuff

People do not use only 10% of their brains. While it is true that a small minority of neurons in the brain are actively firing at any one time, a healthy human will normally use most of their brain over the course of a day, and the inactive neurons are important as well. The idea that activating 100% of the brain would allow someone to achieve their maximum potential and/or gain various psychic abilities is common in folklore and fiction, but doing so in real life would likely result in a fatal seizure. This misconception was attributed to late 19th century leading thinker William James, who apparently used the expression only metaphorically. #learnStuff

The bold, powerful cry commonly associated with the bald eagle in popular culture is actually that of a red-tailed hawk. Bald eagle vocalizations are much softer and chirpier, and bear far more resemblance to the calls of gulls. #learnStuff
