Every time I see reactions similar to what you describe on reality shows, or news footage, or in real life, it always baffles me how poorly so many people react to any level of stress. I often think to myself that I hope that I never have to rely on one of these people to save my life in some kind of an emergency. I am not claiming that I would know exactly what to do in a given situation any more than anyone else as I am not a trained rescue EMT, and I don't expect that from others either. What I do expect is a reasonable response based on thought and logic. If I am in dire need of immediate assistance standing there paralyzed with fear, screaming hysterically, and crying uncontrollably will only result in me dying of neglect.
