Why does Rey Mysterio wear a mask?

For those who don't know, Rey Mysterio is a luchador. Lucha libre is a form of wrestling that is a part of a rich heritage of Mexico. Wrestlers that practice lucha libre are called luchadors and it is customary for luchadors to contest in a mask. The mask these wrestlers dawn define their characters and gimmicks.

Sometimes, a wrestler that has been scheduled to retire, is unmasked after he has lost his final bout. This signifies that his gimmick or character has ended. The wrestling mask is considered "sacred" by all luchadors. If a wrestler is unmasked intentionally during the match, his opponent can be disqualified for the same.

If a wrestler is unmasked, his top priority is to cover his face by any means. Most wrestlers who sport a mask also do so to separate their professional and personal lives, so that people cannot recognize them in public. A few legendary wrestlers are also buried with their masks when they die.
