How do you know that for sure? 5 mins. ? There was a story on here the other day about a young Japanese girl who jumped off her 13th. floor balcony onto hard ground. She layed there alive for three hours before she was found. She later died in the hospital.
Something must have stopped her, she would have fallen on a metal sheet or something before hitting the ground, or her bones were very, very hard, it doesn't make sense, 3 hours of losing blood is something no one can endure, not with the injuries she would have suffered...
I know this because I jumped from a 7th floor and survived landing on my feet, nothing stopped me but they treated me very quickly. They gave me 30 half-litre bags of blood from that moment on and during the 12-hour operation. That's why I know something doesn't add up with the Japanese woman. Open wounds or internal bleeding kill you, imagine the worst possible scenario, my femurs snapped outwards. The good thing is that it didn't hurt...
