Ya Jewskin that's easy to say. But we tell kids all the time not to run in the road, or play in that lake, or go inside the barn that's about to fall over. They do it anyway. They're kids!! And if your childhood was anything like mine, you understand the danger, but...I don't know its just too easy to ignore the advice.
Accidents happen and children die. It is a horrible fact, but it happens. No child on earth made it through childhood without an injury of some kind.
