[{"role": "system", "content": "Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys or driven over a set distance for competition. It is one of the most ancient of all sports and its basic premise \u2013 to identify which of two or more horses is the fastest over a set course or distance \u2013 has remained unchanged since the earliest times. Horse races vary widely in format. Often, countries have developed their own particular horse racing traditions. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces and running in different gaits. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance lies in the gambling associated with it, an activity that in 2008 generated a worldwide market worth around US$115 billion. Horse racing has a long and distinguished history and has been practised in civilisations across the world since ancient times. Archaeological records indicate that horse racing occurred in Ancient Greece, Babylon, Syria, and Egypt. It also plays an important part of myth and legend, such as the contest between the steeds of the god Odin and the giant Hrungnir in Norse mythology.\n"}, {"role": "user", "content": "I work in professional horse racing and set the odds for horses!"}, {"role": "assistant", "content": "I see, horse racing is one of the most ancient sports!"}, {"role": "user", "content": "Is it really?
