Some context: Thalia was born on 26 August 1971, in Mexico City, Mexico. She is the youngest of five daughters of Yolanda Miranda Mange (d. 2011), a painter who was Thalia's manager from 1980 to 1999; and Ernesto Sodi Pallares (d. 1977), a scientist, doctor of pathology, criminologist, and writer. Her four sisters are Laura Zapata (daughter of Guillermo Zapata Perez de Utrera), Federica, Gabriela, and Ernestina Sodi. When she turned one, Thalia appeared in her first TV commercial in Mexico.
In 1981, when Thalia was nine years old, she was incorporated as a vocalist in a children's group named Pac Man, which was formed in order to participate in a popular music festival known as Juguemos a cantar ("Let's play while singing"), a TV program by Televisa. Later, Pac Man changed their band name to "Din-Din". Thalia performed various times along with Din-Din in occasional events and parties, touring all over Mexico. The band recorded a total of 4 studio albums between 1982 and 1983 (En accion, Recordando el Rock and Roll, Somos alguien muy especial and Pitubailando), and later it was disbanded.  After Din-Din broke up in 1984, Thalia participated as a solo artist in two annual music festivals of Juguemos a cantar. In 1984, she placed second there with her interpretation of "Moderna nina del rock" ("Modern rock girl"); this brought her the opportunity to participate in the chorus of the popular musical Vaselina, a child version of the successful musical Grease, in which the band Timbiriche was acting and singing. The line-up of the band consisted of Sasha Sokol, Benny Ibarra, Erik Rubin, Diego Schoening, Mariana Garza and Paulina Rubio. Timbiriche was highly promoted at the time by Televisa, one of the most massive media enterprises globally and the most important in the Spanish-speaking world. Some time later, Thalia obtained the protagonist role of Sandy Dee in the musical, and she performed in 500 theater presentations of Vaselina along with Timbiriche.  In 1986, after the departure of Sasha Sokol from Timbiriche, Thalia became a member of the band. By that time, Timbiriche had already recorded five albums. In the following year, Thalia was invited to participate in the telenovela Pobre senorita Limantour; this production was actually Thalia's debut as a TV actress. However, she appeared in only one episode. In the same year, she recorded with Timbiriche the principal theme of the juvenile telenovela Quinceanera ("Fifteen-year-old"), in which Thalia was the co-protagonist with the role of Beatriz. The TV series was awarded as the "Best telenovela" by "Premios TVyNovelas" in 1988 and Thalia was awarded as "the best new actress of 1988".  With Timbiriche, Thalia recorded four studio albums: Timbiriche VII (1987), the double album Timbiriche VIII & IX (1988) and Los clasicos de Timbiriche (1989). The last one is a compilation of the band's greatest hits, recorded originally in 1987, with new symphonic arrangements as it included the participation of Mexico's philharmonic orchestra. In 1989, Thalia departed from Timbiriche. In that year, she also starred in another TV series, Luz y sombra ("Light and shadow"), which was her first protagonist role. Some time later she visited Los Angeles in order to take English courses in the University of California. She also attended music, singing, acting and dancing classes before beginning her career as a solo artist.

Some context: Elena Vyacheslavovna Mukhina (Russian: Elena Viacheslavovna Mukhina; first name sometimes rendered "Yelena", last name sometimes rendered "Muchina"; June 1, 1960 - December 22, 2006) was a Soviet gymnast who won the all-around title at the 1978 World Championships in Strasbourg, France. Her career was on the rise and she was widely touted as the next great gymnastics star until in 1979 a broken leg left her out of several competitions, and the recovery from that injury combined with pressure to master a dangerous and difficult tumbling move (the Thomas salto) caused her to break her neck just two weeks before the opening of the 1980 Summer Olympics, leaving her permanently quadriplegic just one month past the age of 20.
Mukhina took an interest in gymnastics and figure skating at an early age. When an athletic scout visited her school, she eagerly volunteered to try out for gymnastics. She later joined the CSKA Moscow ("Central Red Army") sports club. In recognition of her accomplishments, Mukhina was inducted into the CSKA Hall of Fame.  Up until 1975, Mukhina was an unremarkable gymnast, and Soviet coaches largely ignored her. Then, two separate incidents brought her skills to the forefront for the Soviet team: Romanian domination of the Soviet gymnastics machine at the 1976 Olympics (for which the director for Soviet women's gymnastics, Larisa Latynina, was blamed; Latynina's response was, "it's not my fault that Nadia Comaneci was born in Romania"); and Mukhina's transition to working with men's coach Mikhail Klimenko, who transformed her into one of the most show-stopping gymnasts of her time. She burst onto the scene at the 1978 World Championships in Strasbourg, France. In one of the most stunning all-around performances in history, she won the gold medal, beating out Olympic Champions Nadia Comaneci and top-ranked Soviet gymnast Nellie Kim, among others. She also tied for the gold medal in the floor exercise event final, as well as winning the silver in balance beam and uneven bars. She made history in this competition by unveiling her signature moves: a full-twisting layout Korbut Flip on bars; a tucked double back salto dismount on beam (a move that is still being used over three decades later); and a full-twisting double back somersault on floor (still an E-rated move in the Code of Points) dubbed the "Muchina". Yet, in spite of these innovations, Mukhina maintained the classic Soviet style, inspired by ballet movements and expressive lines. She quickly established herself as an athlete to watch for at the 1980 Summer Olympics in Moscow.  A documentary film of the Soviet national team (1978) features Mukhina talking with her coach, Mikhail Klimenko, and footage of her rigorous training regimen.
