Answer the question at the end by quoting:

Spitz was born in Modesto, California, the first of three children of Lenore Sylvia (Smith) and Arnold Spitz. His family is Jewish; his father's family was from Hungary and his mother's, originally surnamed "Sklotkovick", were from Russia. When he was two years old, Spitz's family moved to Honolulu, Hawaii, where he swam at Waikiki beach every day. "You should have seen that little boy dash into the ocean.
In 1972, soon after his return to the United States, Spitz landed several lucrative corporate endorsement contracts. He earned about $7 million in a two-year period. However, as the memory of his feats receded, so did his endorsement and promotional deals. As his endorsements faded he started a successful real-estate company in Beverly Hills. He bought a Ferrari and says he made more than $1 million. "A million dollars in 1972 would be equivalent to more than $10 million today," Spitz said. "I did very well, thank you very much." "I would say I was a pioneer. There wasn't anyone who'd gone to the Olympics before me who capitalized the same way on opportunity. It depends on timing, it depends on hype, it depends on the economy, and most importantly, it depends on looks. I mean, I've never seen a magazine of uglies. That's our society. I'm not saying it's right. That's just the facts." Per his official website, Spitz is self-employed as a corporate spokesperson and motivational speaker. However, Sports Yahoo! lists his occupation as a stock broker and motivational speaker. According to a recent interview "Spitz became a stockbroker in 2002 and has since moved into private equity. He is now also dabbling in the "water business," as he calls it, and is in negotiations to build a water-bottling facility on aquifer-rich land that he and a business partner own. He has pursued various entrepreneurial projects with former NBA player Rick Barry. He travels the world delivering about 25 lectures a year. His biography, The Extraordinary Life of An Olympic Champion by Richard J. Foster, was released in July 2008. In July 2012 he endorsed Istanbul's bid to host the 2020 Summer Olympics.

When did his swimming career end?

Some context: Sven Anders Hedin, KNO1kl RVO, (19 February 1865 - 26 November 1952) was a Swedish geographer, topographer, explorer, photographer, travel writer, and illustrator of his own works. During four expeditions to Central Asia, he made the Transhimalaya known in the West and located sources of the Brahmaputra, Indus and Sutlej Rivers. He also mapped lake Lop Nur, and the remains of cities, grave sites and the Great Wall of China in the deserts of the Tarim Basin. In his book Fran pol till pol (From Pole to Pole), Hedin describes a journey through Asia and Europe between the late 1880s and the early 1900s.
Hedin was a monarchist. From 1905 onwards he took a stand against the move toward democracy in his Swedish homeland. He warned of the dangers he assumed to be coming from Czarist Russia, and called for an alliance with the German Empire. Therefore, he advocated a strengthened national defence, with a vigilant military preparedness. August Strindberg was one of his opponents on this issue, which divided Swedish politics at the time. In 1912 Hedin publicly supported the Swedish coastal defense ship Society. He helped collect public donations for the building of the coastal defense ship HSwMS Sverige, which the Liberal and anti-militarist government of Karl Staaff had been unwilling to finance. In early 1914, when the Liberal government enacted cutbacks to the country's defenses, Hedin wrote the Courtyard Speech, in which King Gustaf V promised to strengthen the country's defenses. The speech led to a political crisis that ended with Staaff and his government resigning and being replaced by a non-party, more conservative government. He developed a lasting affinity for the German empire, with which he became acquainted during his formal studies. This is also shown in his admiration for Kaiser Wilhelm II, whom he even visited in exile in the Netherlands. Influenced by imperial Russian and later the Soviet union's attempts to dominate and control territories outside its borders, especially in Central Asia and Turkestan, Hedin felt that Soviet Russia posed a great threat to the West, which may be part of the reason why he supported Germany during both World Wars. He viewed World War I as a struggle of the German race (particularly against Russia) and took sides in books like Ein Volk in Waffen. Den deutschen Soldaten gewidmet (A People in Arms. Dedicated to the German Soldier). As a consequence, he lost friends in France and England and was expelled from the British Royal Geographical Society, and from the Imperial Russian Geographical Society. Germany's defeat in World War I and the associated loss of its international reputation affected him deeply. That Sweden gave asylum to Wolfgang Kapp as a political refugee after the failure of the Kapp Putsch is said to be primarily attributable to his efforts.
What did he write?
A: in which King Gustaf V promised to strengthen the country's defenses.

IN: Overkill is an American thrash metal band, formed in 1980 in New Jersey. They have gone through many line-up changes, leaving bassist D. D. Verni and lead vocalist Bobby "Blitz" Ellsworth as the only constant members. In addition to Verni and Ellsworth, Overkill's current lineup includes Dave Linsk on lead guitar, Derek Tailer on rhythm guitar and Jason Bittner on drums.

1987 marked the release of Overkill's second album Taking Over, the first to be released by Megaforce in cooperation with the major label Atlantic Records. The album featured improved song writing and production and had a somewhat more epic style, showcased in such songs as the anthemic "In Union We Stand". The song was chosen to be Overkill's first music video, used to promote the band through the booming new medium of music television. Another European tour followed, this time opening for Helloween. In late 1987, the !!!Fuck You!!! EP was released, consisting of a studio recording of The Subhumans' song "Fuck You" as well as a handful of live tracks recorded earlier that year in Cleveland. 1987 also saw the departure of drummer Rat Skates. He was replaced by Mark Achabal for a few gigs, then on a permanent basis by European drummer Bob "Sid" Falck,previously of Paul Di'Anno's Battlezone. Overkill released the follow-up to Taking Over, the aptly titled Under the Influence, in 1988. Once again produced by Alex Perialas, Under the Influence was much more raw and thrashy, lacking most of the grand and epic atmosphere of its predecessor. Suffering from rushed writing and production, the album is often regarded as a snapshot and a step backwards for the band. The song "Hello from the Gutter" was released as a single, and the music video gained regular airplay on MTV's Headbangers Ball. Overkill kept up constant touring all over the world, furthering their reputation as one of the most active live metal bands. Overkill released their breakthrough album The Years of Decay in 1989. Produced by Terry Date (Pantera, White Zombie and Soundgarden), the album mixed the raw approach of Under the Influence with more complex song structures and epic elements, resulting in a more serious atmosphere and longer songs, including the eight-minute title track and the ten-minute "Playing With Spiders/Skullkrusher." The uptempo thrasher "Elimination" was released as a single and the music video again received regular airplay on MTV's Headbangers Ball. The song became a fan favorite and has been played live at almost every show since its release. Live support of The Years of Decay took place, in part, on a tour called "Dawn of the Decade" together with label mates Testament.

Did the video win any awards?
