Interesting fact

Horses have a long relationship with humans. Around 50,000 years ago, they were herded for meat, skins and possibly for milk. Evidence suggests that they were first used for farming and transport about 5,000 years ago - more recently than many other farm animals including goats, sheep and cattle.
