A topic relevent to the desire of eternal life is the chance of injury and death as we live our lives. I have heard it said that a necessary thing for all imortal wannabe's to do, is to limit the risk of death that they face. In other words, don't drive fast cars, don't go sky diving, don't get into big wave surfing etc... Shy away from risk.
What I believe in my life, as a general rule, is that a life lived in fear of death, is not a life worth living. See, I want to live forever, but I am not scared of dying. Perhaps I am completely alone here on two fronts. Firstly, I am not scared of death, because as soon as it happens, I believe I won't know anyway, so whats it matter? And secondly, I enjoy fear, I enjoy adrenalin...so increasing my risk in life, makes me feel more alive. I am sure that many people can't relate to that, but for those who can, would it be right for them to limit their risk?
