Chinese water torture
You’re locked in a chair. You can’t move. Every five seconds, a small drop of water drops onto your head.
After being in this situation for twenty minutes, the sound of the water starts to irritate you.
After a week, each drop of water sounds like a drum.
After a month, you feel in pain because you can’t move and the seemingly hurtless drops of water start to open wounds in your head. You can also suffer from labyrinthitis.
After two months, the pain is such that you go insane. If you don’t, well, the drops of water will kill you anyway.
A drop of water. Tiny, frivolous, seemingly innocent… yet it can be the cause of your death.
