Memento Mori reminder.
Memento mori is the medieval Latin theory and practice of reflection on mortality. This daily reminder, set to be launch at the end of each day, is there to remind you than some day you will die. You will then put in perspective everything you do in your life, making sure to make the best out of it. Remember that it doesn't matter how big or important you are, one day you will die like any other living being.
