Someone should write a book titled “Simple Advice For Staying Alive.”

No, really, it’d be full of valuable lessons like: “Don't play with gas around a campfire” and “Stay off the tracks when a train is coming your way.”

Luckily for the girl, a nearby security guard was able to haul her to safety just as the train passed. And luckily for those of us want to write a life lessons book, a nearby witness was able to capture the dramatic rescue on their camera, “giving us this short clip that's enough to make us all rethink our priorities,” as MSN puts it.

[Editor’s note: Although the terrifying rescue at the Corinthians-Itaquera Metro station happened last week, the following video has only recently started to gain some major online traffic]:
