Muay Thai (Thai boxing), the national sport of Thailand, is one of the toughest martial arts in the world. For many people, it secures their livelihood, as it is normal that children fight for tourists and locals for betting purposes. A minimum age for the fighters does not exist. For a pittance, they reach their mental and physical limits with boxing matches. Only a few become a professional boxing idol and earn a lot of money. At the age of 25 their career is usually over.
