Long-reigning middleweight champion Anderson Silva will rematch his rival Chael Sonnen in the main event at UFC 148, and each man is bringing a fistful of intangibles into the cage.

How much of Sonnen's performance can be attributed to elevated testosterone levels? The champ's anger may also play a key role, but in who's favour is yet to be seen.
