Ponce de Leon was rumored to have found the "Fountain of Youth." Was it actually adrenochrome? He explored Florida and Puerto Rico, which is just a hop, skip, and a jump from Haiti and the Dominican Republic -- sound familiar?

Ponce de Leon was Spanish nobility, so he was likely to know about adrenochrome. The "fountain" that he found was likely the indigenous people, which is why any subsequent explorers looking for a fountain or pool of "magic water" never found it. They were looking for the wrong thing.
