Memento Mori v1.0
You can learn more about this extension on my GitHub: https://github.com/mance-rah/memento_mori
The original inspiration for this extension came from a comment I saw online about a Chrome extension that changes New Tabs to show your age, the global population or a countdown to a certain date. The name of the extension is Morality.
Simply put, Memento Mori is a new tab extension that aims to remind the user of the brevity of life. With every new tab, a countdown is shown. This countdown shows you how much time you have left before you die.
