query: How long do horses live?
passage: Horse
Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30years.[7] Uncommonly, a few animals live into their 40s and, occasionally, beyond.[8] The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62.[7] In modern times, Sugar Puff, who had been listed in Guinness World Records as the world's oldest living pony, died in 2007 at age 56.[9]
passage: Büyükada
The conditions in which the horses on the island live and the lack of a treatment centre for horses on the island has been criticised by animal rights groups. According to official figures, 400 horses die each year, although activists consider this to be an underestimate, and claim that the lifespans of the horses on the islands are greatly reduced.
