Pain

Sometimes you have to intentionally inflict pain upon yourself. Sometimes because it's necessary to grow, or it must be done simply to live. You will never see anyone able to endure this amount of pain, let alone inflict it upon themselves.

But this, this is life. There's an important lesson here in this video.

The nerves are very much alive. Not for the faint of heart.
