How Long Can Horses Live? The Oldest Ever Equivalent to Humans Aged 200+
The average lifespan of horses is 25-30 years, only one-third of a human's lifespan, but longer than many other domestic animals. With increasing levels of horse care today, horses are living longer.
Old Billy, born in Britain, is widely recognized as the oldest horse ever. Old Billy was confirmed to be 62 years old when he died. He was born in 1760 in Woolston Lancashire, England, and was once a horse that pulled barges on canals. Old Billy continued to work, even in old age with a curved back, until the new canal opened on February 14, 1821, at which point he retired. That was 61 years old! He died on November 27, 1822.
Old Billy's life was truly a hardworking life!

62 years old, how many years would that be for a human? It's estimated to be about 200 years!

There have been numerous reports and accounts of Old Billy's biography, compiled into a series of 'proofs'. This includes paintings by artists, specimens created, reports from local media, and even news of his death in the 1822 Manchester Year Book. It can be said that the evidence is conclusive!

The head of Old Billy is located at the Manchester Museum. It is a collection of the Manchester Natural History Society, which was founded in 1821. Old Billy's skull was one of its first exhibits on King Street and has been displayed ever since
Old Billy's horse specimen (besides the skull) is located at the Bedford Museum. It was donated in 1932 by auctioneer Harry Pickwoode. It is said that it was sold when the Manchester Natural History Society was in trouble, so the skull and specimen were not in the same museum
Of course, horses need several years to grow completely mature. 3 years is equivalent to a human's adulthood; while physiologically, a 5-year-old horse's body will not fully mature, this period is equivalent to 24.5 years in human age, which is the period of adulthood; a 13-year-old horse has entered the middle age; a 20-year-old horse has entered the elderly age. If your horse reaches 30 years, then he is in an extremely high-age zone; a few horses that exceed 30 years old are absolutely 'longevity stars', a 36-year-old horse is equivalent to a centenarian old man.
