Those who feel meaning in life live longer because they are physically and mentally healthier. This has been scientifically proven many times. But what is behind it?
My conclusion is that life and the universe in general have no meaning or sense. It just exists.
All supposed meanings are artificial and imagined, but that is OK. Any pretended belief works well as the real one. Well, I'll have to pretend to believe in something.
