I'm a sucker for trivia in general, so I'm always on the lookout for interesting facts. This list takes that to a whole other level with random facts that are not only interesting, but also potentially lifesaving. Things like knowing that a red trail from an insect bite or wound means you've got a blood infection and need treatment immediately, or how to recognize the less obvious signs of drowning. This is the kind of knowledge that you hope to never have to use, but should DEFINITELY know.
