The Bajau are a people from Malaysia and Indonesia who make their living diving to depths of 65 feet to collect pearls, clams, and other goodies off the sea bed.
Well, if you're not a professional freediver, and you don't belong to the Bajau people, who can stay underwater for up to 13 minutes, then you can probably only hold your breath around 2 minutes.
The paragraph also includes a quote from a researcher who studies the Bajau, describing them as " a stranger to the land." The third paragraph provides more information on the Bajau and their abilities as divers.
