In the works of Lucretius, we find two reasons why we shouldn't worry about death. If you have had a successful life, Lucretius tell us, there's no reason to mind its end. And, if you haven't had a good time, "Why do you seek to add more years, which would also pass but ill?"

We are tempted to believe that certain achievements and possessions will give us enduring satisfaction.
