Many athletes are covered by insurance in case they suffer an injury that ends their playing career. It may also be an advertising trick, but it's clear that no one knows what could happen.
And the sports world also has many types of insurance purchases.
Japanese food pageant athlete Takeru Kobayashi may not have fully met the typical idea of a professional sports star, but believe it or not, food pageants are often reported by major sports TV stations such as ESPN.
And the owner of eight different Guinness World Records for eating hotdogs, Twinkies, meatballs, tacos, hamburger, ice cream, pasta and pizza is said to have bought insurance for his... stomach for the amount of $100,000.
With Kobayashi in the stomach, Merv Hughes - an Australian cricket player, once spent 370,000 USD to insurance his famous ria chair.
Or NFL star Troy Polamalu, attracted attention around the world in 2010, when it was revealed that he had purchased insurance for his famous curly hair strokes for up to 1 million USD.
Toronto Ultra - Canada's Call of duty e-sports team, with 4 athletes covered with finger insurance for 1 million USD per person.
1 million USD for hair is "crazy", but the numbers will be even larger, many times larger, for the top stars of world sports.
Manuel Neuer of Bayern Munich and the German national team is one of the world's top goalkeepers. And for such a talented person, it is reasonable to protect his tool.
In 2014, Neuer bought insurance for his hands for 3 million Euros, according to the Association of German Insurance Companies. While colleague Iker Cascascas was worried about a further 7 years before, with a contract worth 10 million USD.
The insurance contract provided him with insurance for injuries on or off the pitch, and after signing the contract, he jokingly said: "If there is a knee injury, I will act like my hand is in pain."
For F1 driver Fernando Alonso, who is a loan officer for the Ferrari team, he received insurance for his thumb for an incredible amount of £9 million as part of a comprehensive life and accident insurance package provided by main sponsor Santander.
One of the most famous names in Major League Baseball, in the 1998 record-breaking tournament, Mark' Big Mac' McGwire was paid $12 million for ankle insurance after it turned out to be a persistent injury throughout his career.
Curiously, the insurance contract stipulates that McGwire must use the steroid Androstenedione to prevent further injury. A few years later, Andro was officially banned from playing by Major League Baseball, dragging McGwire into a doping controversy that continues in the tournament to this day.
Venus Williams in tennis, after 2 serious injuries to her wrist, spent 15 million USD to buy insurance for her wrist as a preventative measure.
And for football players, people will see 3 insurance contracts of huge value. First was Cristiano Ronaldo in 2009, when Real Madrid spent £80 million to buy him from Manchester United, but at the same time also invested £90 million to buy insurance for the Portuguese superstar's legs.
In 2006, David Beckham insured his legs for £100 million, setting a new record for the largest personal insurance contract in sports history - so large that it was rumored to have been divided among a number of different insurance companies.
But that record was broken with the arrival of Lionel Messi, who is believed to have bought insurance for his legs for a whopping 750 million Euros - worth three times all the previously mentioned figures combined.
