Elvis Francois, a 47-year-old man who was rescued after being stranded on a boat for 24 days in the Caribbean sea, said he survived by eating ketchup and other random items he found. “I had no food. It was just a bottle of ketchup that was on the boat, garlic powder and Maggi (seasoning) so I mixed it up with some water,” Francois said in a video shared by the navy, Vibe reports.
