I think that we try and live forever because we do not know what is waiting for us in the afterlife or whether we return and live another life. It's full of uncertainty and no one really wants to find out what it is in the end. We grow up knowing that death will come but we want to put it off as long as we can for the simple fact we don't want to die we also want to see our families grow and our children have children and then them have children. We want to see a lot more then we are able to see and so we try and cheat death by eating healthy exercising and doing everything in our power to stay healthy.
Keep up the great work Darkened_Star you have impressed me. I will be looking out for more of your work.
