Today I heard that a person I knew has died.
It was a person that I didn't really know personally. I just saw this person from time to time, until I didn't.
Asking around I found out that person is now dead. Not sure how, but that's the reality.
I chose to think about this as a "memento mori", you can die at any time, you need to make sure you are having an interesting life and that you are having fun at it.
Because at the end of the day, you never know when you are going to die.
