Background: James Alvin Palmer (born October 15, 1945) is a retired American right-handed pitcher who played all of his 19 years in Major League Baseball (MLB) with the Baltimore Orioles (1965-67, 1969-84) and was elected to the Baseball Hall of Fame in 1990. Palmer was the winning pitcher in 186 games in the 1970s, the most wins in that decade by any MLB pitcher. He also won at least twenty games in each of eight seasons and received three Cy Young Awards and four Gold Gloves during the decade. His 268 career victories are currently an Orioles record.
Context: In 1991, Palmer attempted a comeback with the Orioles. Palmer said that he wanted to make sure that he had not retired too early. ESPN, which was trying to cut expenses, had asked him to take a pay cut and to sign a three-year contract. Palmer said he would sign a one-year contract for less pay, but ESPN refused. "I wouldn't be here today if the broadcasting climate had been more to my liking. That was really my prime motivation, the fact that I no longer had that obligation", Palmer said during spring training. Covering Palmer's spring training workouts, Richard Hoffer of Sports Illustrated said that Palmer's comeback was not entirely about money. He wrote that "it is fair to suspect that a certain vanity is involved." Hoffer said that Palmer "has failed to excite either ridicule or astonishment. He's in fabulous condition, no question. But no matter whom he lines up with on the row of practice mounds, there is more pop in the gloves of catchers other than his." While working out at the University of Miami during his comeback attempt, Palmer was approached by Miami assistant coach Lazaro Collazo. Collazo reportedly told him, "You'll never get into the Hall of Fame with those mechanics." "I'm already in the Hall of Fame", Palmer replied. To help Palmer's pitching motion, Collazo and Palmer completed unusual drills that involved Palmer placing a knee or foot on a chair as he tossed the ball. After giving up five hits and two runs in two innings of a spring training game, he retired permanently. Palmer said that he tore his hamstring while warming up for the game, commenting, "I'm not saying I wouldn't like to continue, but I can't", he said. "I heard something pop in my leg yesterday. It wasn't a nice sound. I don't know what that means, but I think it's going to play havoc with my tennis game." He retired with a 268-152 win-loss record and a 2.86 ERA.
Question: Why did he have a comeback?
Answer: Palmer said that he wanted to make sure that he had not retired too early.

Background: Chris Austin Hadfield (born 29 August 1959) is a retired Canadian astronaut who was the first Canadian to walk in space. An engineer and former Royal Canadian Air Force fighter pilot, Hadfield has flown two space shuttle missions and served as commander of the International Space Station. Hadfield, who was raised on a farm in southern Ontario, was inspired as a child when he watched the Apollo 11 Moon landing on TV. He attended high school in Oakville and Milton and earned his glider pilot licence as a member of the Royal Canadian Air Cadets.
Context: Hadfield attended White Oaks Secondary School in Oakville, Ontario until his senior year and then graduated as an Ontario Scholar from Milton District High School in 1977. As a member of the Royal Canadian Air Cadets, he earned a glider pilot scholarship at age 15 and a powered pilot scholarship at age 16. After graduating from high school in 1978, he joined the Canadian Armed Forces and spent two years at Royal Roads Military College followed by two years at the Royal Military College, where he received a bachelor's degree in mechanical engineering in 1982. Before graduating, he also underwent basic flight training at CFB Portage la Prairie. In 1983, he took honours as the top graduate from Basic Jet Training at CFB Moose Jaw, and then went on to train as a tactical fighter pilot with 410 Tactical Fighter Operational Training Squadron at CFB Cold Lake, flying the Canadair CF-116 Freedom Fighter and the McDonnell Douglas CF-18 Hornet. After completing his fighter training, Hadfield flew CF-18 Hornets with 425 Tactical Fighter Squadron, flying intercept missions for NORAD. He was the first CF-18 pilot to intercept a Soviet Tupolev Tu 95 long-range bomber in the Canadian Arctic. In the late 1980s, Hadfield attended the US Air Force Test Pilot School at Edwards Air Force Base and served as an exchange officer with the US Navy at Strike Test Directorate at the Patuxent River Naval Air Station. His accomplishments from 1989 to 1992 included testing the McDonnell Douglas F/A-18 Hornet and LTV A-7 Corsair II aircraft; performing research work with NASA on pitch control margin simulation and flight; completing the first military flight of F/A-18 enhanced performance engines; piloting the first flight test of the National Aerospace Plane external burning hydrogen propulsion engine; developing a new handling qualities rating scale for high angle-of-attack test; and participating in the F/A-18 out-of-control recovery test program. In May 1992, Hadfield graduated with a master's degree in aviation systems from the University of Tennessee Space Institute, where his thesis concerned high-angle attack aerodynamics of the F/A-18 Hornet fighter jet. In total, Hadfield has flown over 70 different types of aircraft.
