Problem: Background: Hooker's date of birth is a subject of debate; the years 1912, 1915, 1917, 1920, and 1923 have been suggested. Most sources give 1917, though at times Hooker stated he was born in 1920. Information in the 1920 and 1930 censuses indicates that he was born in 1912. In 2017, a series of events took place to celebrate the purported centenary of his birth.
Context: Beginning in 1962, Hooker gained greater exposure when toured Europe in the annual American Folk Blues Festival. His "Dimples" became a successful single on the UK Singles Charts in 1964, eight years after its first US release. Hooker began to perform and record with rock musicians. One of his earliest collaborations was with British blues rock band the Groundhogs. In 1970, he recorded the joint album Hooker 'n Heat, with the American blues and boogie rock group Canned Heat, whose repertoire included adaptations of Hooker songs. It became the first of Hooker's albums to reach the Billboard charts, peaking at number 78 on the Billboard 200. Other collaboration albums soon followed, including Endless Boogie (1971) and Never Get Out of These Blues Alive (1972), which included Steve Miller, Elvin Bishop, Van Morrison, and others. Hooker appeared in the 1980 film The Blues Brothers. He performed "Boom Boom" in the role of a street musician. In 1989, he recorded the album The Healer with Carlos Santana, Bonnie Raitt, and others. The 1990s saw additional collaboration albums: Mr. Lucky (1991), Chill Out (1995), and Don't Look Back (1997) with Morrison, Santana, Los Lobos, and additional guest musicians. His re-recording of "Boom Boom" (the title track for his 1992 album) with guitarist Jimmie Vaughan became Hooker's highest charting single (number 16) in the UK. Come See About Me, a 2004 DVD, includes performances filmed between 1960 and 1994 and interviews with several of the musicians. Hooker died in his sleep on June 21, 2001, in Los Altos, California. He is interred at the Chapel of the Chimes in Oakland, California. He was survived by eight children, 19 grandchildren, and numerous great-grandchildren.
Question: Did he slow down before his death?
Answer: The 1990s saw additional collaboration albums:

IN: Grace Brewster Murray Hopper (nee Murray; December 9, 1906 - January 1, 1992) was an American computer scientist and United States Navy rear admiral. One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first compiler related tools. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, an early high-level programming language still in use today. Hopper had attempted to enlist in the Navy during World War II, but she was rejected by the military because she was 34 years of age and thus too old to enlist.

In accordance with Navy attrition regulations, Hopper retired from the Naval Reserve with the rank of commander at age 60 at the end of 1966. She was recalled to active duty in August 1967 for a six-month period that turned into an indefinite assignment. She again retired in 1971 but was again asked to return to active duty in 1972. She was promoted to captain in 1973 by Admiral Elmo R. Zumwalt, Jr. After Republican Representative Philip Crane saw her on a March 1983 segment of 60 Minutes, he championed H.J.Res. 341, a joint resolution originating in the House of Representatives, which led to her promotion to commodore by special Presidential appointment. She remained on active duty for several years beyond mandatory retirement by special approval of Congress. Effective November 8, 1985, the rank of commodore was renamed rear admiral (lower half) and Hopper became one of the Navy's few female admirals. Following a career that spanned more than 42 years, Admiral Hopper took mandatory retirement from the Navy on August 14, 1986. At a celebration held in Boston on the USS Constitution to commemorate her retirement, Hopper was awarded the Defense Distinguished Service Medal, the highest non-combat decoration awarded by the Department of Defense. At the time of her retirement, she was the oldest active-duty commissioned officer in the United States Navy (79 years, eight months and five days), and had her retirement ceremony aboard the oldest commissioned ship in the United States Navy (188 years, nine months and 23 days). (Admirals William D. Leahy, Chester W. Nimitz, Hyman G. Rickover and Charles Stewart were the only other officers in the Navy's history to serve on active duty at a higher age. Leahy and Nimitz served on active duty for life due to their promotions to the rank of fleet admiral.)

When did she retire?

OUT: at the end of 1966.

Background: Departures (Japanese: okuribito, Hepburn: Okuribito, "one who sends off") is a 2008 Japanese drama film directed by Yojiro Takita and starring Masahiro Motoki, Ryoko Hirosue, and Tsutomu Yamazaki. Loosely based on Coffinman, a memoir by Shinmon Aoki, the film follows a young man who returns to his hometown after a failed career as a cellist and stumbles across work as a nokanshi--a traditional Japanese ritual mortician. He is subjected to prejudice from those around him, including from his wife, because of strong social taboos against people who deal with death. Eventually he earns their respect and learns the importance of interpersonal connections through the beauty and dignity of his work.
Context: Japanese funerals are highly ritualized affairs which are generally--though not always--conducted in accordance with Buddhist rites. In preparation for the funeral, the body is washed and the orifices are blocked with cotton or gauze. The encoffining ritual (called nokan), as depicted in Departures, is rarely performed, and even then only in rural areas. This ceremony is not standardized, but generally involves professional morticians (Na Guan Shi , nokanshi) ritually preparing the body, dressing the dead in white, and sometimes applying make-up. The body is then put on dry ice in a casket, along with personal possessions and items necessary for the trip to the afterlife. Despite the importance of death rituals, in traditional Japanese culture the subject is considered unclean as everything related to death is thought to be a source of kegare (defilement). After coming into contact with the dead, individuals must cleanse themselves through purifying rituals. People who work closely with the dead, such as morticians, are thus considered unclean, and during the feudal era those whose work was related to death became burakumin (untouchables), forced to live in their own hamlets and discriminated against by wider society. Despite a cultural shift since the Meiji Restoration of 1868, the stigma of death still has considerable force within Japanese society, and discrimination against the untouchables has continued. Until 1972, most deaths were dealt with by families, funeral homes, or nokanshi. As of 2014, about 80% of deaths occur in hospitals, and preparation of the bodies is frequently done by hospital staff; in such cases, the family often does not see the body until the funeral. A 1998 survey found that 29.5% of the Japanese population believed in an afterlife, and a further 40% wanted to believe; belief was highest among the young. Belief in the existence of a soul (54%) and a connection between the worlds of the living and the dead (64.9%) was likewise common.
