Life. Enough said.
Life isn't what it seems. Life isn't even the unexpected. Is there a higher power? Does the paranormal exist? Few have found out the answers to these questions. And the second they know, they die. That's just how it works.
The good and curious will always die first. And the rest will lead out boring, uneventful lives. This is why life is unfair.
Look the unknown in the face and challenge it, and you're in for the most exciting and shortest life you can have.
