19 Places Where Nature Can Kill You in Seconds

These places were not invented. They are not in movies. They exist right now, accessible, real, on this planet. A river in the Amazon that boils at 99 degrees. A cave in Mexico where your lungs fill with water in ten minutes. A stream in England that no one has ever walked away from. Some of them welcome tourists. In all of them, the human body can die in no time at all. Not because of an accident. Just because that's what they do.
