Moss was born in London, son of Alfred Moss, a dentist of Bray, Berkshire, and Aileen (nee Craufurd). He was brought up at Long White Cloud house on the right bank of the River Thames. His father was an amateur racing driver who had placed 16th at the 1924 Indianapolis 500. Stirling was a gifted horse rider as was his younger sister, Pat Moss, who became a successful rally driver and married Erik Carlsson.
Although ostensibly retired from racing since 1962, Moss did make a number of one-off appearances in professional motorsport events in the following two decades. He also competed in the 1974 London-Sahara-Munich World Cup Rally in a Mercedes-Benz, but retired from the event in the Algerian Sahara. The Holden Torana he shared with Jack Brabham in the 1976 Bathurst 1000 was hit from behind on the grid and eventually retired with engine failure. Moss, at the wheel of the Torana when the V8 engine let go, was criticised by other drivers for staying on the racing line for over  2/3  of the 6.172 km long circuit while returning to the pits as the car was dropping large amounts of oil onto the road. He also shared a Volkswagen Golf GTI with Denny Hulme in the 1979 Benson & Hedges 500 at Pukekohe Park Raceway in New Zealand.  In 1980 he made a comeback to regular competition, in the British Saloon Car Championship with the works-backed GTi Engineering Audi team. For the 1980 season Moss was the team's number two driver to team co-owner Richard Lloyd. For the 1981 season Moss stayed with Audi, as the team moved to Tom Walkinshaw Racing management, driving alongside Martin Brundle.  Throughout his retirement he raced in events for historic cars, driving on behalf of and at the invitation of others, as well as campaigning his own OSCA FS 372 and other vehicles.  On 9 June 2011 during qualifying for the Le Mans Legends race, Moss announced on Radio Le Mans that he had finally retired from racing, saying that he had scared himself that afternoon. He was 81.

Martina Hingis (born 30 September 1980) is a Swiss former professional tennis player who spent a total of 209 weeks as the singles world No. 1 and 90 weeks as doubles world No. 1, holding both No. 1 rankings simultaneously for 29 weeks. She won five Grand Slam singles titles, thirteen Grand Slam women's doubles titles, winning a calendar-year doubles Grand Slam in 1998, and seven Grand Slam mixed doubles titles; for a combined total of twenty-five major titles. In addition, she won the season-ending WTA Finals two times in singles and three times in doubles, and an Olympic silver medal.
In 2001, Switzerland, with Hingis and Roger Federer on its team, won the Hopman Cup. Hingis didn't drop a set in any of her singles matches during the event, defeating Tamarine Tanasugarn, Nicole Pratt, Amanda Coetzer, and Monica Seles. Federer was later quoted as saying: "I learned a lot from her, especially the two years I was here - once as a hitting partner and once as a partner with Martina. Definitely she helped me to become the player I am today."  Hingis reached her fifth consecutive Australian Open final in 2001, defeating both of the Williams sisters en route, before losing to Jennifer Capriati. She briefly ended her coaching relationship with her mother Melanie early in the year but had a change of heart two months later just before the French Open. 2001 was her least successful year in several seasons, with only three tournament victories in total. She lost her No. 1 ranking for the last time (to Jennifer Capriati) on 14 October 2001. In that same month, Hingis underwent surgery on her right ankle.  Coming back from injury, Hingis won the Australian Open doubles final at the start of 2002 (again teaming with Anna Kournikova) and reached a sixth straight Australian Open final in singles, again facing Capriati. Hingis led by a set and 4-0 and had four match points but lost in three sets. In May 2002, she needed another ankle ligament operation, this time on her left ankle. After that, she continued to struggle with injuries and was not able to recapture her best form.  In February 2003, at the age of 22, Hingis announced her retirement from tennis, due to her injuries and being in pain. "I want to play tennis only for fun and concentrate more on horse riding and finish my studies." In several interviews, she has indicated she wishes to return to her home country and coach full-time.  During this segment of her tennis career, Hingis won 40 singles titles and 36 doubles events. She held the World No. 1 singles ranking for a total of 209 weeks (fifth most following Steffi Graf, Martina Navratilova (after whom she was named), Chris Evert, and Serena Williams). In 2005, Tennis magazine put her in 22nd place in its list of 40 Greatest Players of the TENNIS era.
