"He had 720 hours and absolutely no distractions – and he’d use that time to improve himself. 'How can I give myself a better sugar scrub ... how can I stretch it deeper, how can I be more calm, how can I be more patient?' he says.... With so much time and only himself for company, Alati’s thoughts were a source of entertainment and a lifeline. 'The thoughts would just come to you, and if you don’t make sure that they go in a good direction, they can spiderweb out of control and lead you to a bad place,' Alati says.... '[Prisoners in solitary] are not given a bathtub with sugar scrubs, and essential oil and food, and a yoga mat. They’re not given that stuff, so if I didn’t have that stuff, and I wasn’t actually free and I wasn’t being paid, that’s why [it would be a] punishment.'... When he finally emerged, the noise and commotion was overwhelming.... Friends and family surrounded him, and social interaction was 'a bit of a culture shock.' He was surprised by the number of choices he had and that social niceties needed to be observed. 'I knew how to do everything – I just forgot,' Alati says. 'I can’t just start doing push-ups on a bathtub in front of people. I can’t just start walking around with no underwear.'"

"Hallucinations and $100,000: the poker player who shut himself in a pitch-black room for weeks/Rich Alati had a six-figure sum in his sights. As long as he could survive 30 days in the dark with no human contact" (The Guardian).
ADDED: Alati had control: If he could stay in, he'd get $100,000 and if he came out he'd lose $100,000. That's $200,000 of incentive, for a 30-day effort. The other guy, Young, could only wait and see what Alati would do. Young's advantage was that he didn't have to do anything difficult, and he might win $100,000. One alternative was that Young could communicate by audio with Alati and make an offer to end it earlier. And that's what happened, with Young paying $62,400 for Alati's 20 days in the bathroom.
Was there any real danger that Alati would lose his mind? If so, Young faced the risk of having to feel bad about what he'd lured Alati to do, and Alati risked suffering that would extend beyond the 30 day period. But Alati also stood to gain from the 30-day experience. There was the enforced meditation in solitude and the chance to see what visions grow in darkness. And then there was all that physical exercise. You'd do a lot of push-ups and sit-ups. It would be fun to look at yourself in the mirror after all that, no?
