The Moken people of Thailand possess the remarkable ability to hold their breath for 5 minutes underwater and can free dive to a depth of 30 metres. Known as the Sea Gypsies, these indigenous people have led the same way of life for over 3000 years along the coastline of the Andaman Sea. Today, their existence is precarious, as the seas they rely on are depleted and development threatens the beaches they have lived on for millennia.
