Problem: Bjorn Borg was born in Stockholm, Sweden, on 6 June 1956, as the only child of Rune and Margaretha Borg. He grew up in nearby Sodertalje. As a child, Borg became fascinated with a golden tennis racket that his father won at a table-tennis tournament. His father gave him the racket, beginning his tennis career.

Borg had one of the most distinctive playing styles in the Open Era. He played from the baseline, with powerful ground-strokes. His highly unorthodox backhand involved taking his racket back with both hands but actually generating his power with his dominant right hand, letting go of the grip with his left hand around point of contact, and following through with his swing as a one-hander. He hit the ball hard and high from the back of the court and brought it down with considerable topspin, which made his ground strokes very consistent. There had been other players, particularly Rod Laver and Arthur Ashe, who played with topspin on both the forehand and backhand, yet Laver and Ashe used topspin only as a way to mix up their shots to pass their opponents at the net easily. Borg was one of the first top players to use heavy topspin on his shots consistently. Complementing his consistent ground-strokes was his fitness. Both of these factors allowed Borg to be dominant at the French Open. One of the factors that made Borg unique was his dominance on the grass courts of Wimbledon, where baseliners since World War II did not usually succeed. Some experts attributed his dominance on this surface to his consistency, an underrated serve, equally underrated volleys, and his adaptation to grass courts. Against the best players, he almost always served-and-volleyed on his first serves (but he naturally played from the baseline after his second serves). Another trait usually associated with Borg is his grace under pressure. His calm court demeanor earned him the nickname of the "Ice Man" or "Ice-Borg." Borg's physical conditioning was legendary and unrivalled. He could outlast most of his opponents under the most grueling conditions. Contrary to popular belief, however, this wasn't due to his exceptionally low resting heart rate, often reported to be near 35 beats per minute. In his introduction to Borg's autobiography My Life and Game, Eugene Scott relates that this rumor arose from a medical exam the 18-year-old Borg once took for military service, where his pulse was recorded as 38. Scott goes on to reveal Borg's true pulse rate as "about 50 when he wakes up and around 60 in the afternoon." Borg is credited with helping to develop the style of play that has come to dominate the game today.

When did he wrote his autobiography?

Problem: Maurice Robert "Mike" Gravel (; born May 13, 1930) is an American politician who was a Democratic United States Senator from Alaska from 1969 to 1981 and a candidate in the 2008 U.S. presidential election. Born and raised in Springfield, Massachusetts, by French-Canadian immigrant parents, Gravel served in the U.S. Army in West Germany, and he later graduated from the Columbia University School of General Studies. He moved to Alaska in the late 1950s, becoming a real estate developer and entering politics. He served in the Alaska House of Representatives from 1963 to 1966 and also became Speaker of the Alaska House.

In the late 1960s and early 1970s the U.S. Department of Defense was in the process of performing tests for the nuclear warhead for the Spartan anti-ballistic missile. Two tests, the "Milrow" and "Cannikin" tests, were planned, involving the detonation of nuclear bombs under Amchitka Island in Alaska. The Milrow test would be a one megaton calibration exercise for the second, and larger five megaton, Cannikin test, which would measure the effectiveness of the warhead. Gravel opposed the tests in Congress. Before the Milrow test took place in October 1969, he wrote that there were significant risks of earthquakes and other adverse consequences, and called for an independent national commission on nuclear and seismic safety to be created; he then made a personal appeal to President Nixon to stop the test. After Milrow was conducted, there was continued pressure on the part of environmental groups against going forward with the larger Cannikin test, while the Federation of American Scientists claimed that the warhead being tested was already obsolete. In May 1971, Gravel sent a letter to U.S. Atomic Energy Commission hearings held in Anchorage, in which he said the risk of the test was not worth taking. Eventually a group not involving Gravel took the case to the U.S. Supreme Court, which declined to issue an injunction against it, and the Cannikin test took place as scheduled in November 1971. Gravel had failed to stop the tests (notwithstanding his later claims during his 2008 presidential campaign). Nuclear power was considered an environmentally clean alternative for the commercial generation of electricity and was part of a popular national policy for the peaceful use of atomic energy in the 1950s and 1960s. Gravel publicly opposed this policy; besides the dangers of nuclear testing, he was a vocal critic of the Atomic Energy Commission, which oversaw American nuclear efforts, and of the powerful United States Congress Joint Committee on Atomic Energy, which had a stranglehold on nuclear policy and which Gravel tried to circumvent. In 1971, Gravel sponsored a bill to impose a moratorium on nuclear power plant construction and to make power utilities liable for any nuclear accidents; in 1975, he was still proposing similar moratoriums. By 1974, Gravel was allied with Ralph Nader's organization in opposing nuclear power. Six months before U.S. Secretary of State Henry Kissinger's secret mission to the People's Republic of China (P.R.C.) in July 1971, Gravel introduced legislation to recognize and normalize relations with China, including a proposal for unity talks between the P.R.C. and the Republic of China (Taiwan) regarding the Chinese seat on the U.N. Security Council. Gravel reiterated his position in favor of recognition, with four other senators in agreement, during Senate hearings in June 1971.
