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.
Horse Isle (video game)
"Horse Isle" also introduced a new version of Legend of the Esrohs called Life Cycle in 2012. The game has the same virtual world but the focus is now on breeding. In Life Cycle your horses can age, breed and die. This is the only difference between the two servers.
