YouTube star MrBeast has tested his endurance with an extreme stunt that saw him reduced to tears and sparked fears for his mental and physical health.
The online star, whose real name is Jimmy Donaldson, was buried alive in a specially-built coffin for seven days, monitored around the clock by cameras.
He was out to beat the record he set two years ago when he spent 50 hours below ground.
Donaldson was equipped with food and water and his custom-made home had enough room for limited movement, but found the greatest challenge was mental.
He became emotional at several points and told friends that he was going through “mental agony” as they rallied to keep his spirits up with jokes and stunts as they communicated through walkie-talkies.
