Earlier this year, Reg Hyde didn't see the sky or breathe fresh air for 28 days straight. He was shut away with a handful of men, far from his loved ones, in a small pressurised chamber bobbing in the remote ocean. If he'd escaped outside, he would most likely have died. "It feels like prison sometimes," the Filipino Australian told The Feed. But Reg, 28, says he loves this life, because it takes him somewhere he believes is the world's most intriguing place: the bottom of the ocean.
