Normally, when a person meets a box jellyfish, the result is near instant death for the human. But Rachel not only survived her encounter; several months later, she's doing reasonably well. Her surprising story of survival has led at least one professor to credit her with being a medical marvel.The amazing thing is that, the girl didn't get stung just once, but many times! Miracle? Who knows, but I've always heard from Fire Fighters, EMTs, and Paramedics, that if it isn't your time to die, then it isn't your time.
Something like this makes me want to rethink the way hit points, wounds, and saving throws work.
