A Mortal Girl in a Denial World

I heard on the news today that a vast percentage of worldwide deaths are caused by non-communicable diseases, such as heart disease, liver failure, cancer, and the chronic pulmonary disease. The term being bandied about was "premature death." What does this term really mean anyway? I have heard that premature death refers to anyone dying earlier that the statistical average for their demographic group (they have different numbers for men, women, Hispanic, etc). This concept seems ludicrous to me. Life and death are very complex and personal matters. What will be fatal for one person will not be for the next. People with very similar lifestyles and genetics may have decades between their last days. Under what foolishness is it that we pretend we will know when we are "supposed" to die? Now don't get me wrong - I am in no hurry to die and I appreciate that medicine is working to help keep us all alive longer, I really do. Because I'm sure if I was told I was dying at this age I would surely and absolutely see it as premature. But I wonder if we are all sort of participating in a epic farce. We are all mortal. We are all doing to die. Something, someday, will cause us to breathe our last breath. This is inevitable. How much of what we call medicine is really trying to escape this inevitable fate?
