This is the stoic philosophy of Memento Mori. It comes from the Latin phrase "Remember you must die." It is a reminder that all of us, one day, must die. A famous quote from Marcus Aurelius perfectly portrays this idea: "You could leave life right now. Let that determine what you do and say and think. Westmon Works Memento Mori Bracelet set captures that idea for you to carry with you every day with an adjustble bracelet with skull and a wallet sized remberance card.
