Some context: Gennady Golovkin was born on April 8, 1982, in the city of Karaganda in the Kazakh SSR, Soviet Union (now Karagandy, Kazakhstan) to a Russian coal miner and Korean mother, who worked as an assistant in a chemical laboratory. He has three brothers, two elder named Sergey and Vadim and a twin, Max. Sergey and Vadim had encouraged Golovkin to start boxing when Golovkin was eight years old. As a youth, Golovkin would walk the streets with them, who went around picking fights for him with grown men.
After ending his amateur career in 2005, Golovkin signed a professional deal with the Universum Box-Promotion (UBP) and made his professional debut in May 2006. By the end of 2008, Golovkin's record stood at 14-0 (11 KO) and while he had few wins over boxers regarded as legitimate contenders, he was regarded as one of the best prospects in the world. Golovkin was given 4 more relatively easy bouts in 2009. In 2010, Universum started to run into financial issues after having been dropped by German television channel ZDF. This caused a number of issues for Golovkin who was effectively unable to fight in Germany, and contract disputes between the two parties got complicated.  Golovkin terminated his contract with Universum in January 2010 and stated the following in an interview: "The reason for this decision is that I've always been placed behind Felix Sturm and Sebastian Zbik by Universum. Our demands to fight against Felix Sturm or Sebastian Zbik have been always rejected on absurd grounds. Universum had no real plan or concept for me, they did not even try to bring my career forward. They would rather try to prevent me from winning a title as long as Sturm and Zbik are champions. Further more, bouts against well-known and interesting opponents were held out in prospect, but nothing happened. This situation was not acceptable. It was time to move forward."  After cutting ties with Universum, the WBA issued an interim title fight between Golovkin, ranked #1 at the time, and Milton Nunez. Golovkin routed Nunez, defeating him in 58 seconds to become a world champion. Golovkin was promptly upgraded to WBA (Regular) champion. He tried to fight WBA (Super) champion Felix Sturm and Hassan N'Dam N'Jikam during this time, but was unable to get them in the ring. Oleg Hermann, Golovkin's manager, said "It is very hard to find a good opponent. Everybody knows that Felix Sturm is afraid of Gennady. Strictly speaking, Sturm should get out of boxing and become a marathon runner because he is running fast and long. He has an excellent chance to become a champion in athletics."

Some context: Benjamin Solomon Carson Sr. (born September 18, 1951) is an American neurosurgeon, author and politician serving as the 17th and current United States Secretary of Housing and Urban Development since 2017, under the Trump Administration. Prior to his cabinet position, he was a candidate for President of the United States in the Republican primaries in 2016. Born in Detroit, Michigan, and a graduate of Yale University and the University of Michigan Medical School, Carson has authored numerous books on his medical career and political stances.
By ninth grade, the family's financial situation had improved, his mother surprising neighbors by paying cash to buy a new Chrysler car, and the only government assistance they still relied on was food stamps. Carson attended the predominantly black Southwestern High School for ninth through 12th grades, graduating third in his class academically. In high school he played the baritone horn in the band, and participated in forensics (public speaking), chess club, and the U.S. Army Junior Reserve Officers' Training Corps (JROTC) program where he reached its highest rank--cadet colonel. Carson served as a laboratory assistant in the high school's biology, chemistry, physics school laboratories beginning in 10th, 11th, and 12th grade, respectively, and worked as a biology laboratory assistant at Wayne State University the summer between 11th and 12th grades.  In his book Gifted Hands, Carson relates that as a youth he had a violent temper. "As a teenager, I would go after people with rocks, and bricks, and baseball bats, and hammers," Carson told NBC's Meet the Press in October 2015. He said he once tried to hit his mother on the head with a hammer over a clothing dispute, while in the ninth grade he tried to stab a friend who had changed the radio station. Fortunately, the blade broke in his friend's belt buckle. Carson said that the intended victim, whose identity he wants to protect, was a classmate, a friend, or a close relative. After this incident, Carson said that he began reading the Book of Proverbs and applying verses on anger. As a result, he states he "never had another problem with temper". In his various books and at campaign events, he repeated these stories and said he once attacked a schoolmate with a combination lock. Nine friends, classmates, and neighbors who grew up with him told CNN in 2015 they did not remember the anger or violence he has described. In response, Carson posted on Facebook a 1997 Parade Magazine issue, in which his mother verified the stabbing incident. He then questioned the extent of the effort CNN had exerted in the investigation.  He has said that he protected white students in a biology lab after a race riot broke out at his high school in response to the assassination of Martin Luther King Jr. in 1968. The Wall Street Journal confirmed the riot but could not find anyone who remembered Carson sheltering white students.
