Problem: Background: Howard Duane Allman (November 20, 1946 - October 29, 1971) was an American guitarist, session musician, and co-founder and leader of the Allman Brothers Band until his death following a motorcycle crash in 1971, at the age of 24. The Allman Brothers Band was formed in Jacksonville, Florida, in 1969. The band had great success in the early 1970s. Allman is best remembered for his brief but influential tenure in the band and in particular for his expressive slide guitar playing and inventive improvisational skills.
Context: Duane Allman was born on November 20, 1946, in Nashville, Tennessee. He was the eldest son of Willis Allman (1918-1949), a World War II non-commissioned officer turned recruiting officer in the United States Army, and Geraldine Allman (nee Robbins) (1917-2015). His brother, Gregg, was born on December 8, 1947. On December 26, 1949, when the family was living near Norfolk, Virginia, Willis Allman was murdered. In order to retrain as an accountant, Geraldine "Mama A" Allman sent Duane and Gregg to Castle Heights Military Academy in Lebanon, Tennessee, which they both disliked intensely. In 1957, the family moved to Daytona Beach, Florida, where the boys attended Seabreeze High School. The boys returned to Nashville to spend summers with their grandmother, and there Gregg learned guitar basics from a neighbor. In 1960, he had saved enough money to buy his first guitar, a Japanese-made Teisco Silvertone, while Duane acquired a Harley 165 motorbike. Despite Duane being left-handed, he played the guitar right-handed. Duane began to take an interest in the guitar, and the boys would sometimes fight over it, until Duane wrecked the motorbike and traded it for a Silvertone of his own. His mother eventually bought Duane a Gibson Les Paul Junior. It was also in Nashville that the boys became musically inspired by a rhythm and blues concert where they saw blues guitar legend B. B. King perform. Duane told Gregg, "We got to get into this." Duane learned to play very quickly and soon became the better guitarist of the two.
Question: How did that happen?
Answer:

IN: John Harvey Kellogg, M.D. (February 26, 1852 - December 14, 1943) was an American medical doctor, nutritionist, inventor, health activist, and businessman. He was the director of the Battle Creek Sanitarium in Battle Creek, Michigan. The sanitarium was founded by members of the Seventh-day Adventist Church. It combined aspects of a European spa, a hydrotherapy institution, a hospital and a high-class hotel.

Although they are less discussed than his food creations, Kellogg designed and improved upon a number of medical devices that were regularly used at the Battle Creek Sanitarium in surgical operations and in treatment modalities falling under the term "physiotherapy". Many of the machines invented by Kellogg were manufactured by the Battle Creek Sanitarium Equipment Company, which was established in 1890. Dr. Kellogg attempted to popularize these treatment methods, including electrotherapy, hydrotherapy, and motor therapy, in his work The Home Handbook of Domestic Hygiene and Rational Medicine, first published in 1881. As he specialized in certain gynecological surgeries (particularly hemorrhoidectomies and ovariotomies) and gastrointestinal surgeries, he developed various instruments for these operations. These included specialized hooks and retractors, a heated operating table, and an aseptic drainage tube used in abdominal surgery. Additionally, Kellogg took keen interest in devising instruments for light therapy, mechanical exercising, proper breathing, and Hydrotherapy. His medical inventions spanned a wide range of applications and included a hot air bath, vibrating chair, oscillomanipulator, window tent for fresh air, pneumograph to graphically represent respiratory habits, loofah mitt, and an apparatus for home sterilization of milk. Some of his inventions were fashionable enough to be included in the first class gymnasium of the RMS Titanic. As in other areas, Dr. Kellogg did not make concerted efforts to profit from his medical inventions. Kellogg's statement in 1916 about his food company sheds light on his general motivations: "I desire to make clear...that the food business I have been carrying on is a part of my general scheme to propagate the ideas of health and biological living. Otherwise, I should not have engaged in it as a commercial enterprise, but I have carried it on as a part of the general philanthropic work in which I was engaged."

What medical breakthroughs did he make

OUT: Kellogg took keen interest in devising instruments for light therapy, mechanical exercising, proper breathing, and Hydrotherapy.

Background: Larsson was born in Helsingborg, Scania. His father, Francisco Rocha, is from Cape Verde, and his mother, Eva Larsson, is Swedish. His parents, who never married and split up when he was 12, decided that he should take his mother's surname because they felt it would make it easier for their son to be accepted in Sweden. He credits his father for his love of football.
Context: Shortly after rejoining Helsingborg, Larsson was signed on loan by Manchester United from 1 January until 12 March 2007, coinciding with the Allsvenskan's off-season. He scored on his debut against Aston Villa in the FA Cup third round on 7 January 2007 at Old Trafford. Larsson scored his first ever FA Premier League goal on 31 January in a 4-0 win over Watford. While United were eager to extend the loan deal, Larsson stated that he had made a promise to his family and his club to return on 12 March. This was confirmed on 20 February, when Larsson announced that he would not be extending his loan period. Despite this, Sir Alex Ferguson was full of praise for the striker, who scored 3 goals in 13 matches in all competitions during his three-month stay, saying, "He's been fantastic for us, his professionalism, his attitude, everything he's done has been excellent." "We would love him to stay but, obviously, he has made his promise to his family and Helsingborg and I think we should respect that - but I would have done anything to keep him." Larsson scored Manchester United's only goal in their win against Lille at Old Trafford in the Champions League. He made his final appearance for United on 10 March in an FA Cup sixth round tie away to Middlesbrough, ending in a 2-2 draw. Manchester United won the Premier League two months after Larsson had left the club, and although he had not played the required quota of ten league games to qualify for a Premier League winners medal, he, alongside Alan Smith, was granted special dispensation by the Premier League after the club requested extra medals for the two. Larsson's last appearance at Old Trafford in fact came against United, the day after his loan with the club expired, as captain for a Europe XI team in the UEFA Celebration Match. Larsson received a standing ovation from the home fans upon being substituted for Liverpool player Robbie Fowler.
