Elizabeth oversaw the restoration of the remote Castle of Mey, on the north coast of Scotland, which she used to "get away from everything" for three weeks in August and ten days in October each year. She developed her interest in horse racing, particularly steeplechasing, which had been inspired by the amateur jockey Lord Mildmay in 1949. She owned the winners of approximately 500 races. Her distinctive colours of blue with buff stripes were carried by horses such as Special Cargo, the winner of the 1984 Whitbread Gold Cup, and Devon Loch, which spectacularly halted just short of the winning post at the 1956 Grand National and whose jockey Dick Francis later had a successful career as the writer of racing-themed detective stories. Peter Cazalet was her trainer for over 20 years. Although (contrary to rumour) she never placed bets, she did have the racing commentaries piped direct to her London residence, Clarence House, so she could follow the races. As an art collector, she purchased works by Claude Monet, Augustus John and Peter Carl Fabergé, among others.In February 1964, Elizabeth had an emergency appendectomy, which led to the postponement of a planned tour of Australia, New Zealand and Fiji until 1966. She recuperated during a Caribbean cruise aboard the royal yacht, Britannia. In December 1966, she underwent an operation to remove a tumour after she was diagnosed with colon cancer. Contrary to rumours, she did not have a colostomy. She was diagnosed with breast cancer in 1984 and a lump was removed from her breast. Her bouts with cancer were never made public during her lifetime.In 1982, Queen Elizabeth was rushed to hospital when a fish bone became stuck in her throat, and had an operation to remove it. Being a keen angler, she calmly joked afterwards, "The salmon have got their own back." Similar incidents occurred at Balmoral in August 1986, when she was hospitalised at Aberdeen Royal Infirmary overnight but no operation was needed, and May 1993, when she was admitted to the Infirmary for surgery under general anaesthetic.In 1975, Queen Elizabeth visited Iran at the invitation of Shah Mohammad Reza Pahlavi. The British ambassador and his wife, Anthony and Sheila Parsons, noted how the Iranians were bemused by her habit of speaking to everyone regardless of status or importance, and hoped the Shah's entourage would learn from the visit to pay more attention to ordinary people. Between 1976 and 1984, she made annual summer visits to France, which were among 22 private trips to continental Europe between 1963 and 1992.In 1987, Queen Elizabeth was criticised when it emerged that two of her nieces, Katherine and Nerissa Bowes-Lyon, had both been committed to a psychiatric hospital because they were severely handicapped. However, Burke's Peerage had listed the sisters as dead, apparently because their mother, Fenella (the Queen Mother's sister-in-law), "was 'extremely vague' when it came to filling in forms and might not have completed the paperwork for the family entry correctly". When Nerissa died the year before, her grave was originally marked with a plastic tag and a serial number. The Queen Mother said that the news of their institutionalisation came as a surprise to her.
