Problem: Background: Charles Parker Jr. (August 29, 1920 - March 12, 1955), also known as Yardbird and Bird, was an American jazz saxophonist and composer. Parker was a highly influential jazz soloist and a leading figure in the development of bebop, a form of jazz characterized by fast tempos, virtuosic technique and advanced harmonies. Parker was a blazingly fast virtuoso, and he introduced revolutionary harmonic ideas including rapid passing chords, new variants of altered chords, and chord substitutions. His tone ranged from clean and penetrating to sweet and somber.
Context: Parker's life was riddled with depression and heroin addiction. This addiction caused him to miss performances and be considered unemployable. He frequently resorted to busking, receiving loans from fellow musicians and admirers, and pawning his saxophones for drug money. Heroin use was rampant in the jazz scene, and users could acquire it with little difficulty. Although he produced many brilliant recordings during this period, Parker's behavior became increasingly erratic. Heroin was difficult to obtain once he moved to California, where the drug was less abundant, so he used alcohol as a substitute. A recording for the Dial label from July 29, 1946, provides evidence of his condition. Before this session, Parker drank a quart of whiskey. According to the liner notes of Charlie Parker on Dial Volume 1, Parker missed most of the first two bars of his first chorus on the track, "Max Making Wax". When he finally did come in, he swayed wildly and once spun all the way around, away from his microphone. On the next tune, "Lover Man", producer Ross Russell physically supported Parker. On "Bebop" (the final track Parker recorded that evening) he begins a solo with a solid first eight bars; on his second eight bars, however, he begins to struggle, and a desperate Howard McGhee, the trumpeter on this session, shouts, "Blow!" at him. Charles Mingus considered this version of "Lover Man" to be among Parker's greatest recordings, despite its flaws. Nevertheless, Parker hated the recording and never forgave Ross Russell for releasing it. He re-recorded the tune in 1951 for Verve. Parker's life took a turn for the worst when his 2 year old daughter tragically passed away from pneumonia. He attempted suicide twice in 1954, which landed him in a mental hospital. When Parker received his discharge from the hospital, he was clean and healthy. Before leaving California, he recorded "Relaxin' at Camarillo" in reference to his hospital stay. He returned to New York, resumed his addiction to heroin and recorded dozens of sides for the Savoy and Dial labels, which remain some of the high points of his recorded output. Many of these were with his so-called "classic quintet" including Davis and Roach.
Question: Was he having health issues
Answer: Parker's life was riddled with depression and heroin addiction.

Problem: Background: Odom was born in South Jamaica, Queens, New York City, to Joe Odom and Cathy Mercer. His father was a heroin addict, and Odom's mother died of colon cancer when he was twelve years old. At her deathbed, Odom's mom told him: "Be nice to everybody". Afterwards, he was raised by his maternal grandmother, Mildred Mercer.
Context: On December 11, 2011, Odom was traded to the Dallas Mavericks, the defending NBA champions, for a first-round draft pick and an $8.9 million trade exception after NBA Commissioner David Stern vetoed a proposed three-team trade that would have sent Odom and Houston Rockets teammates Kevin Martin, Luis Scola, and Goran Dragic to the New Orleans Hornets; Chris Paul to the Lakers; and Pau Gasol to the Houston Rockets. Odom felt "disrespected" after he learned of the Hornets trade publicly, and he requested a trade from the Lakers to another contending team. The Lakers were also concerned that Odom's contract was pricey since he was not needed to initiate the triangle offense with Mike Brown replacing Phil Jackson as Lakers coach. In January 2012, Sports Illustrated reported that "Odom [had] yet to find his niche in Dallas. His struggles [made] him a frequent target of [Mavericks coach Rick] Carlisle, who [harped] on Odom's need to understand the coverages, be more alert, communicate and get in better shape... Team sources say Odom...appeared stressed by what they believe [was] the mental burden of an overwhelming offseason." On March 2, 2012, Odom was assigned to the Texas Legends of the NBA D-League. He had missed the prior three games due to personal reasons. His stint with the Legends was canceled on March 3, 2012, and he returned to the Mavs' active roster. On March 24, Odom did not play in a 104-87 loss to the San Antonio Spurs; this was the first time he could remember not playing due to a coach's decision. On April 9, 2012, it was announced that Odom had parted ways with the Mavericks. Instead of releasing him, the team listed Odom as inactive for the remainder of the season. The move allowed the Mavericks to trade him at the end of the season. In a statement to ESPN, Odom said, "I'm sorry that things didn't work out better for both of us, but I wish the Mavs' organization, my teammates and Dallas fans nothing but continued success in the defense of their championship." Mavericks owner Mark Cuban admitted that a clash between the two during halftime in a game against the Memphis Grizzlies on April 7 was the last straw. Odom reportedly responded angrily when Cuban questioned his commitment, asking if he was "in or out." Odom averaged only 6.6 points in 20.5 minutes along with career lows in shooting percentage (35.2), rebounds (4.2) and assists (1.7) .
