One of the most misleading things about our world today is the increased sense of comfort we feel. Yes, on average planes crash less. Yes, diseases have been cured. Yes, infant mortality rates have made progress. Yes, crime is down. But the slow and steady increase in life expectancy obscures some very critical realities.

First off, the fact that the average man in the United States now lives to be 76 and the average woman lives to be 81 does nothing about the fact that the clock of nuclear annihilation currently sits at two minutes to midnight. Second, averages do nothing for the individual. You can still get hit by a bus crossing the street. You can still fall off a ladder. You can still be the non-smoker who gets lung cancer. The odds might not make that likely, just as they don’t make winning the lottery or getting struck by lightning likely, but again, these things happen all the time.

The purpose of pointing this out is not to scare you or contribute to your anxiety. It’s simply a reminder that there is nothing fair about black swans and randomness. It’s why the Stoics wanted us to always be aware of the possibilities of Fortune and to remember that we “could leave life right now.” It’s why they knew that Memento Mori was so important to understand.

When you realize that our existence hangs by a thread, you are empowered. You seize the moment. You don’t sweat the silly things that other people worry about. You take more risks, better risks, not fewer. Because you have true perspective. Because you don’t take your years and your safety for granted.

And hopefully you will live every one of those 75+ years and enjoy them all. But if not, you’re fine too.
