Horse
Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, beyond. The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62. 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.
American Quarter Horse Association
On the racetrack, AQHA offers year-end Champion awards in age and sex divisions, plus broodmare, distance horse, Canadian champion, owner, breeder, trainer, and jockey. Thus there is a champion two-year-old colt, filly and gelding plus champion two-year-old from the preceding. The three-year-old and aged categories work the same way, with the World Champion being chosen from the winners of the age and sex divisions. In addition to the year end awards, there are three lifetime awards - Race Register of Merit, Superior Race Horse and Supreme Race Horse. A Register of Merit is awarded when a horse attains a speed index of 80 or above. A Superior Race Horse is achieved when the horse earns 200 racing points. A Supreme Race Horse award requires the horse to satisfy the following three criteria - 1) win over $500,000.00 in earnings, 2) win two Grade 1 stakes races and 3) win a total of ten races.
