"It Quickly Leads To Amputation And Death": 31 Terrifying Human Body Facts That I Refused To Believe Were Real, Until I Literally Fact-Checked Them

Summary: The human body is amazing, but it can also be a little scary. A doctor's daughter fact-checked some of the most terrifying body facts shared online, and the results are wild. For example, some people's immune systems glitch, making them allergic to their own sweat or causing their body to attack its own healthy organs. Also, every single day, your body makes hundreds of cell mistakes that could turn into cancer, though it usually fixes them before they cause harm. Even scarier are "prions"—tiny brain proteins that can fold incorrectly and cause incurable brain damage. One prion disease is fatal insomnia, where your brain completely forgets how to sleep until you pass away. Finally, modern medicine can sometimes keep people alive long past the point of having a good quality of life.
