Problem: Background: Bruce Lee was born on November 27, 1940, at the Chinese Hospital, in San Francisco's Chinatown. According to the Chinese zodiac, Lee was born in both the hour and the year of the Dragon, which according to tradition is a strong and fortuitous omen. Lee and his parents returned to Hong Kong when he was three months old. Bruce's father, Lee Hoi-chuen, (Li Hai Quan ) was Han Chinese, and his mother, Grace Ho (He Ai Yu ), was of Eurasian ancestry.
Context: At 172 cm (5 ft 8 in) and weighing 64 kg (141 lb) at the time, Lee was renowned for his physical fitness and vigor, achieved by using a dedicated fitness regimen to become as strong as possible. After his match with Wong Jack Man in 1965, Lee changed his approach toward martial arts training. Lee felt that many martial artists of his time did not spend enough time on physical conditioning. Lee included all elements of total fitness--muscular strength, muscular endurance, cardiovascular endurance, and flexibility. He used traditional bodybuilding techniques to build some muscle mass, though not overdone, as that could decrease speed or flexibility. At the same time, with respect to balance, Lee maintained that mental and spiritual preparation are fundamental to the success of physical training in martial arts skills. In Tao of Jeet Kune Do he wrote, Training is one of the most neglected phases of athletics. Too much time is given to the development of skill and too little to the development of the individual for participation. ... JKD, ultimately is not a matter of petty techniques but of highly developed spirituality and physique. According to Linda Lee Cadwell, soon after he moved to the United States, Lee started to take nutrition seriously and developed an interest in health foods, high-protein drinks, and vitamin and mineral supplements. He later concluded that achieving a high-performance body was akin to maintaining the engine of a high-performance automobile. Allegorically, as one could not keep a car running on low-octane fuels, one could not sustain one's body with a steady diet of junk food, and with "the wrong fuel", one's body would perform sluggishly or sloppily. Lee also avoided baked goods and refined flour, describing them as providing empty calories that did nothing for his body. He was known for being a fan of Asian cuisine for its variance, and often ate meals with a combination of vegetables, rice, and fish, and drank fresh milk.
Question: How does Bruce stay fit?
Answer: Lee included all elements of total fitness

Background: Born in Nelson County, Virginia, Allen was the son of Loretta M. and Earl Raymond Allen, who was recorded in the 1920 and 1930 U.S. census records for Wayne County, Michigan as working as a chauffeur to a private family. He earned varsity letters in football, track and basketball at Lake Shore High School in St. Clair Shores, Michigan; having graduated in 1940. Allen went to Alma College in Michigan and later at Marquette University in Milwaukee, Wisconsin, where he was sent as an officer trainee in the U. S. Navy's World War II V-12 program. He graduated with a B.S. in education from Michigan State Normal College (now Eastern Michigan University) in Ypsilanti, and then attended the University of Michigan in Ann Arbor, where he earned his master's degree in physical education in 1947.
Context: After rejecting a $1 million, four-year contract offer throughout the 1977 season, Allen was dismissed by the Redskins in mid-January. He was replaced by one of his favorite players, Jack Pardee, by then the promising young head coach of the Bears, who had gained the wild card playoff berth ahead of the Redskins; both had finished at 9-5. Rams owner Carroll Rosenbloom was searching for a new coach after parting ways with Chuck Knox, and decided to bring Allen back. Allen's hiring was announced on February 1, and he returned to Los Angeles in 1978 with much media fanfare. His second stint as the Rams' head coach was an unfortunate experience for all concerned. Unlike his first stint, Allen did not have full authority over personnel. He thus worked with general manager Don Klosterman to oversee a talented roster that had made the team a perennial playoff challenger. Allen brought with him his scrupulous discipline and attention to detail, which extended to practice-field protocol and dining-hall decorum. However, his coaching style did not play well with the new generation of NFL players, and a group of Ram players chafed at the regulations almost immediately. Some made their grievances public; a few, including standout linebacker Isiah Robertson, briefly left camp. As newspaper reports were quoting players expressing confidence that differences would be resolved, the Rams played listlessly and lost the first two games of the 1978 exhibition schedule. Rosenbloom decided that for the season to be salvaged a change must be made, and the announcement of Allen's abrupt dismissal was made on August 13. Many of Allen's own players were surprised by the decision. Defensive coordinator Ray Malavasi, well-respected and liked by players (and the only holdover from Chuck Knox' staff), replaced him; the Rams ultimately advanced to that year's NFC Championship Game and the following year to the Super Bowl. Rosenbloom died in April 1979. Allen soon joined CBS Sports as an analyst for NFL network telecasts, and worked in the broadcast booth from 1978 to 1983. With former Cleveland Browns great running back Jim Brown and play-by-play announcer Vin Scully, they were the network's only three-man announcing team.
