"TIL that in 1518, in the small French town of Strasbourg, a young woman named Frau Troffea started dancing uncontrollably in the street. Her dancing continued for days & on the 3rd day, her shoes were soaked with blood. She attracted 30+ people to join her, which catalyzed the Dancing Plague of 1518."
Just because you don't believe something doesn't mean it isn't true. You could try Googling things before you make claims. This is one of the things I found in mere seconds, and there's more of it out there if you want to read about it:
"Humans share nearly 50 percent of their DNA with fungi, and we contract many of the same viruses as fungi. If we can identify the natural immunities that fungi have developed, we can extract them to help humans."
