How long does icelandic horses live?

Answer 1

The breed matures late. The horses are not usually ridden until they are four years old, and structural development is not complete until age seven. Their most productive years are between eight and eighteen, although they retain their strength and stamina into their twenties. An Icelandic mare that lived in Denmark reached a record age of 56,[4] while another horse, living in Great Britain, reached the age of 42.[9] The horses are highly fertile, and both sexes are fit for breeding up to age 25; mares have been recorded giving birth at age 27.
