Being active is an important part of life, and it keeps people healthier and happier. These days, there are numerous sports to choose from. Some you have probably heard of, but others you haven't. One sport that doesn't get as much attention as it used to is boxing. It is a tough sport and not for everyone because it involves fighting. It is a battle unlike anything else in sports. Boxing has been around for ages, but the sport took a big turn in the late 1800s. It went from bare-knuckle fights to gloved events. That was also when James L. Sullivan became a household name and a boxing hero. He was the first US sports millionaire and won almost every match in his entire career. Moving ahead in time, Joe Louis is a boxing legend still commonly talked about today. In a time of segregation, Louis was loved by both black and white fans. He helped fight against the color barrier and won the heavyweight title in 1937. He holds the record for successfully defending the title 25 times.
