Biggest, oldest, heaviest... the record breakers.
The 57th version of best-selling reference book also features new entries for the shortest bull, the oldest gymnast and the lowest ever car.
Being published in 22 languages in more than 100 countries, the 2013 Guinness World Records is expected to sell around 2.7 million copies and documents numerous new extremes relating to the human body.
These include 86-year-old Johanna Quaas, a retired PE teacher from Leipzig, Germany, who is named the oldest gymnast; Egyptian-born Moustafa Ismail, recognised for having the largest "guns" - biceps and triceps - with a circumference of 25.5in; and London-based sumo wrestler Sharran Alexander, who weighs 203.21kg (32st), who was named the world's heaviest sportswoman.
