Question:
Usher was born in Dallas, Texas, the son of Jonetta Patton (nee O'Neal), from Tennessee, and Usher Raymond III. Usher spent the majority of his young life in Chattanooga: his father left the family when Usher was a year old. Usher grew up with his mother, then-stepfather, and half-brother, James Lackey (born 1984). Directed by his mother, Usher joined the local church youth choir in Chattanooga, when he was nine years old.
Aside from recording music, Usher is involved in other businesses, including several restaurants. In 2007 Usher worked with Richard Herpin and Honoring Blanc for the fragrances Usher He and Usher She. The promotion for the fragrance, featured Usher and Martha Stewart in the Macy's, "The Magic of Macy's" commercial. In September 2008 Usher released the fragrances, UR for Men and UR for Women. Usher fifth fragrance, VIP was launched in 2009.  On March 30, 2015, it was announced that Usher is a co-owner, with various other music artists, in the music streaming service Tidal. The service specialises in lossless audio and high definition music video with curated editorial. Jay Z acquired the parent company of Tidal, Aspiro, in the first quarter of 2015. The slogan "Turn the tide" and the hashtag "#TIDALforAll" was used by various artists on social media during the buildup to the press conference relaunching the service. Usher, along with sixteen artist stakeholders (such as Alicia Keys, Kanye West, Beyonce, Rihanna, Madonna, J.Cole, Nicki Minaj and more) co-own Tidal, with the majority owning a 3% equity stake. The idea of having an all artist owned streaming service was created by those involved to adapt to the increased demand for streaming within the current music industry, and to rival other streaming services such as Spotify, which have been criticised for their low payout of royalties."The challenge is to get everyone to respect music again, to recognize its value", stated Jay-Z on the release of Tidal.  On June 28, 2015, Usher became partners with Yoobi the fast-growing school supplies company called based out of Los Angeles. The company donates a portion of its products to schools and has brought in over $20 million in revenue between June 2014 and June 201 Yoobi CEO Ido Leffler told Inc. The Usher line of supplies with Yoobi features a collaboration with Jonni Cheatwood, the artist who does the designing. The slogan is "Mixing street smarts with school smarts". The collection is available online and at Targets nationwide, and for every purchase, school supplies are donated to kids in need in US classrooms. When asked why he partnered with Yoobi, Usher said, "Preparing future leaders through my New Look Foundation has always been about having the proper tools to succeed in life. If they don't have the tools, young men and women from underserved communities can't even begin to understand the idea of having a new or different perspective. So that's where this collaboration came together giving young people the tools and supplying them with hope."

Answer the question at the end by quoting:

Frasier Winslow Crane is a fictional character on the American television sitcoms Cheers and Frasier, portrayed by Kelsey Grammer. Grammer received award recognitions for portraying this character in these two shows, in addition to a 1992 one-time appearance in Wings. The character debuts in the Cheers third-season premiere, "Rebound (Part 1)" (1984), as Diane Chambers's love interest, part of the Sam and Diane story arc. Intended to appear for only a few episodes, Grammer's performance for the role was praised by producers, prompting them to expand his role and to increase his prominence.
In 1993, after Cheers ended, Frasier and Lilith (Bebe Neuwirth) divorce offscreen, and Lilith is awarded custody of their son Frederick, with Frasier granted visiting rights. In the pilot "The Good Son", Frasier explains that he left Boston because he felt that his life and career had grown stagnant (and he had been publicly humiliated after climbing onto a ledge and nearly committing suicide before being talked down). Therefore, he returned to his original hometown of Seattle, where his father Martin (John Mahoney) and brother Niles (David Hyde Pierce) live, to begin a fresh start.  Frasier works for the radio station, KACL, as the host of his psychotherapeutic radio show, The Dr. Frasier Crane Show, produced by his producer and friend, Roz Doyle (Peri Gilpin), who has many ex-boyfriends. Later, his father Martin, a retired Seattle Police Department detective who was shot in the line of duty, ends up moving in with him. Frasier becomes concerned about his father in his current state as he can barely walk, and requires a cane to move. In Cheers, Frasier says that his father is dead, and that he was a scientist. He also says that he is an only child. This inconsistency is later explained in "The Show Where Sam Shows Up": At Frasier's apartment, Sam Malone tells Martin and Niles what Frasier had said about them, and Frasier explains that he was trying to distance himself from his family at the time. In Cheers, Frasier tells bar patrons that he is an orphan. He confirms in "To All the Girls I've Loved Before" (1988) that his mother Hester, portrayed by Nancy Marchand in "Diane Meets Mom" (1984) and then by Rita Wilson in flashbacks in "Mamma Mia" (1999) and "Don Juan in Hell: Part 2" (2001), is dead off-screen.  Frasier hires a live-in physical therapist, Daphne Moon (Jane Leeves), to look after Martin. Daphne is an eccentric, working class Englishwoman who professes to be "a bit psychic". Moreover, Martin brings his beloved Jack Russell Terrier, Eddie, whom Frasier despises. After some initial apprehension, Frasier grows very close to his new family.  In "IQ" (season six, episode 19), he is revealed to have been an Oxford University alumnus besides being a Harvard alumnus. In the same episode, he is said to have scored 129 in a school IQ test (his brother Niles scored 156).

Why does he hire a live in  physical therapist?
to look after Martin.
