Researchers in Aberdeen think playing Wii Fit may improve the elderly's balance and lower risks of falling.

The University of Aberdeen, Scotland and the UK's National Health Service (NHS) have embarked on a four month study on people over 70 to observe any changes in balance after regular use of the Wii Fit.

The video game has different activities including yoga poses, push ups, strength, balance and aerobic exercises.

The Wii Fit includes a balance board that records movements and gives feedback on performance.

Dr Marie Fraser, a specialist registrar at Woodend Hospital in Scotland, UK, is carrying out the research.

She told CNN: "Falls are the most common cause of accidental injury in older people and the most common cause of accidental deaths in 75-year-olds and over."

It is hoped that using the Wii Fit's balance board can improve elderly people's balance and confidence.

Dr Alison Stewart, who devised the study said she came up with the idea while working in the Osteoporosis department at the University of Aberdeen, after seeing a large number of fractures in old people who had fallen.

Stewart, a commercial research manager with the NHS, said she then decided to research how to improve older people's balance.

She told CNN: "There exists a medical fitness device that improves balance, but it is expensive and I could not get the funding. 1. What is the study about?

Muslims believe the Quran was verbally revealed by God to Muhammad through the angel Gabriel (Jibril), gradually over a period of approximately 23 years, beginning on 22 December 609 CE, when Muhammad was 40, and concluding in 632, the year of his death. Muslims regard the Quran as the most important miracle of Muhammad, a proof of his prophethood, and the culmination of a series of divine messages that started with the messages revealed to Adam and ended with Muhammad. The word "Quran" occurs some 70 times in the text of the Quran, although different names and words are also said to be references to the Quran.

According to the traditional narrative, several companions of Muhammad served as scribes and were responsible for writing down the revelations. Shortly after Muhammad's death, the Quran was compiled by his companions who wrote down and memorized parts of it. These codices had differences that motivated the Caliph Uthman to establish a standard version now known as Uthman's codex, which is generally considered the archetype of the Quran known today. There are, however, variant readings, with mostly minor differences in meaning. 1. What is the name of the book?

Toyota is the world's market leader in sales of hybrid electric vehicles, and one of the largest companies to encourage the mass-market adoption of hybrid vehicles across the globe. Cumulative global sales of Toyota and Lexus hybrid passenger car models achieved the 10million milestone in January 2017. Its Prius family is the world's top selling hybrid nameplate with over 6million units sold worldwide .

The company was founded by Kiichiro Toyoda in 1937, as a spinoff from his father's company Toyota Industries to create automobiles. Three years earlier, in 1934, while still a department of Toyota Industries, it created its first product, the Type A engine, and its first passenger car in 1936, the Toyota AA. Toyota Motor Corporation produces vehicles under five brands, including the Toyota brand, Hino, Lexus, Ranz, and Daihatsu. It also holds a 16.66% stake in Subaru Corporation, a 5.9% stake in Isuzu, as well as joint-ventures with two in China (GAC Toyota and Sichuan FAW Toyota Motor), one in India (Toyota Kirloskar), one in the Czech Republic (TPCA), along with several "nonautomotive" companies. TMC is part of the Toyota Group, one of the largest conglomerates in the world.

Toyota is headquartered in Toyota City, Aichi. The main headquarters of Toyota is located in a 4-storey building in Toyota. As of 2006, the head office has the "Toyopet" Toyota logo and the words "Toyota Motor". The Toyota Technical Center, a 14-story building, and the Honsha plant, Toyota's second plant engaging in mass production and formerly named the Koromo plant, are adjacent to one another in a location near the headquarters. Vinod Jacob from "The Hindu" described the main headquarters building as "modest". In 2013, company head Akio Toyoda reported that it had difficulties retaining foreign employees at the headquarters due to the lack of amenities in the city. 1. Where is Toyota's headquarters?
