Background: Ronald Wilson Reagan was born on February 6, 1911 in an apartment on the second floor of a commercial building in Tampico, Illinois. He was the younger son of Nelle Clyde (nee Wilson; 1883-1962) and Jack Reagan (1883-1941). Jack was a salesman and storyteller whose grandparents were Irish Catholic emigrants from County Tipperary, while Nelle was of half English and half Scottish descent (her mother was born in Surrey). Reagan's older brother, Neil Reagan (1908-1996), became an advertising executive.
Context: After completing 14 home-study Army Extension Courses, Reagan enlisted in the Army Enlisted Reserve and was commissioned a second lieutenant in the Officers' Reserve Corps of the Cavalry on May 25, 1937.  On April 18, 1942, Reagan was ordered to active duty for the first time. Due to his poor eyesight, he was classified for limited service only, which excluded him from serving overseas. His first assignment was at the San Francisco Port of Embarkation at Fort Mason, California, as a liaison officer of the Port and Transportation Office. Upon the approval of the Army Air Forces (AAF), he applied for a transfer from the cavalry to the AAF on May 15, 1942, and was assigned to AAF Public Relations and subsequently to the First Motion Picture Unit (officially, the "18th Army Air Force Base Unit") in Culver City, California. On January 14, 1943, he was promoted to first lieutenant and was sent to the Provisional Task Force Show Unit of This Is the Army at Burbank, California. He returned to the First Motion Picture Unit after completing this duty and was promoted to captain on July 22, 1943.  In January 1944, Reagan was ordered to temporary duty in New York City to participate in the opening of the Sixth War Loan Drive, which campaigned for the purchase of war bonds. He was reassigned to the First Motion Picture Unit on November 14, 1944, where he remained until the end of World War II. He was recommended for promotion to major on February 2, 1945, but this recommendation was disapproved on July 17 of that year. While with the First Motion Picture Unit in 1945, he was indirectly involved in discovering actress Marilyn Monroe. He returned to Fort MacArthur, California, where he was separated from active duty on December 9, 1945. By the end of the war, his units had produced some 400 training films for the AAF.

Background: Lewis Allan Reed (March 2, 1942 - October 27, 2013) was an American musician, singer, and songwriter. He was the lead guitarist, singer and principal songwriter for the rock band the Velvet Underground, with a solo career that spanned five decades. The Velvet Underground achieved little commercial success during their existence, but are now regarded as one of the most influential bands in rock, underground, and alternative music. After leaving the band in 1970, he released 20 solo studio albums.
Context: Throughout the 1970s Reed was a heavy user of methamphetamine and alcohol.  Metal Machine Music (1975) was an hour of modulated feedback and guitar effects. Critics interpreted it as a gesture of contempt, an attempt to break his contract with RCA or to alienate his less sophisticated fans. Reed claimed that the album was a genuine artistic effort, even suggesting that quotations of classical music could be found buried in the feedback. Lester Bangs declared it "genius", though also psychologically disturbing. The album was reportedly returned to stores by the thousands and was withdrawn after a few weeks.  1976's Coney Island Baby still drew on the underbelly of city life. At this time his lover was a transgender woman, Rachel, mentioned in the dedication of "Coney Island Baby" and appearing in the photos on the cover of Reed's 1977 "best of" album, Walk on the Wild Side: The Best of Lou Reed. Rock and Roll Heart was his 1976 debut for his new record label Arista, and Street Hassle (1978) was released in the midst of the punk scene he had helped to inspire. Reed took on a watchful, competitive and sometimes dismissive attitude towards punk. Aware that he had inspired them, he regularly attended shows at CBGB to track the artistic and commercial development of numerous punk bands, and a cover illustration and interview of Reed appeared in the first issue of Punk by Legs McNeil.  In 1978 Reed released his third live album, Live: Take No Prisoners, which some critics thought was his "bravest work yet," while others considered it his "silliest." Rolling Stone described it as "one of the funniest live albums ever recorded" and compared Reed's monologues with those of Lenny Bruce. Reed felt it was his best album to date.  The Bells (1979) featured jazz trumpeter Don Cherry. Around this period Reed also appeared as a sleazy record producer in Paul Simon's film One-Trick Pony. From around 1979 Reed began to wean himself off drugs.

Background: Yen was born in Guangzhou, China. His mother, Bow-sim Mark, is a Fu Style Wudangquan (internal martial arts) and Tai Chi grandmaster, while his father, Klyster Yen (Zhen Yun Long ), is a newspaper editor. When he was two years old, his family moved to Hong Kong and then to Boston when he was 11. His younger sister, Chris Yen, is also a martial artist and actress, and appeared in the 2007 film Adventures of Johnny Tao: Rock Around the Dragon.
Context: Yen describes himself as a mixed martial artist. He learned Tai Chi from a young age under his mother's tutelage. He then wanted to learn Taekwondo in his teenage years, earning a 6th Dan in the process. At the time, the Beijing Wushu Team had a scout in the United States and invited Yen over to Beijing, China, where he began training at the Beijing Sports Institute, the same facility where champion-turned-actor Jet Li trained; this is where the two of them crossed paths for the first time.  Upon his return to the United States, Yen won gold medals in various wushu competitions.  Yen later went on to discover and seek knowledge on other martial arts styles; he would later obtain black and purple belts from judo and Brazilian Jiu-Jitsu, respectively, and went on to study the art of Parkour, Wrestling, Muay Thai, Kickboxing and Boxing under various trainers. His exposure to mixed martial arts (MMA) was heightened when he went back to the United States from 2000 to 2003. While making his Hollywood debut, he also took time off to learn the various martial arts forms. Yen's progress was evident when he returned to Asia, where he implemented his newfound knowledge of MMA, showcased in films such as SPL: Sha Po Lang (2005), Flash Point (2007), and Special ID (2013).  Near the end of 2007, Yen added a new martial arts system to his arsenal. He was offered the role of Wing Chun grandmaster and mentor of film star Bruce Lee, Ip Man, in a 2008 film named after the grandmaster. He worked hard and studied Wing Chun under Ip Man's eldest son, Ip Chun, for 9 months before tackling the role. Ip Chun has since praised Yen for his effort, his skills as a martial artist, and his ability to grasp the full concept of Wing Chun much faster than anyone else he has taught.  Yen believes that combining many martial arts together will produce the most effective and harmonious style. Yen has said, "When you watch my films, you're feeling my heart." He believes in practical combat, and in his opinion, MMA is the most authentic type of practical combat. He has mentioned that he would have competed in the Ultimate Fighting Championship if he did not have a recurring shoulder injury.
Question: How did he come to this style?
Answer:
to discover and seek knowledge on other martial arts styles; he would later obtain black and purple belts from judo and Brazilian Jiu-Jitsu,
