Some perspective: Anderson Silva has spent more days as the Ultimate Fighting Championship’s middleweight titleholder than 27 United States Presidents spent in office.

The incomparable 37-year-old Brazilian became champion on Oct. 14, 2006, when he brutalized Rich Franklin en route to a first-round technical knockout at UFC 64. More than 2,000 days have passed since. Silva has successfully defended the 185-pound title nine times. No other champion in UFC history had more than six defenses.
