Taekwondo star Steven Lopez to fight in record 5th Olympics (Yahoo Sports)

The first time Steven Lopez made the U.S. Olympic taekwondo team, he was just 15 years old. More than two decades later, the Texas-based fighter recently qualified again and will likely be the oldest athlete competing in taekwondo at the Rio de Janeiro games. At 37, Lopez is the most acclaimed fighter in the sport and dominated the Korean martial art for more than a decade, winning a record five world championship titles.
