A scientist claims he has increased his lifespan by 20 percent after living 93 days underwater.

Joseph Dituri, 55, a retired Naval officer, has been living inside a 100-square-foot pod at the bottom of the Atlantic Ocean for 93 days, researching how a pressurized environment impacts the human body.

The mission was also designed to beat the world record for living underwater — the previous stay was 73 days.
