One of the worlds greatest pleasures is secret knowledge. Things you learn that your peers don't know, or imagine you know. Its the lifetime batting average of every member of the Yankees, stats of Desert Storm, or the names and home-worlds of legions of Superheroes. Commit this knowledge to memory, and you can speak the private language of those who have approached this with equal dedication.
The will of the warrior is the resolute acceptance of death - Musashi
