Sorry my humor didn't go over with you. So I will be real. This guy was a Green Beret. He is trained to handle different kinds of torture. If he was placed in Gitmo or some other secret CIA interrogation camp and subjected to sleep deprivation, extreme air conditioning, ear-rattling music and sounds, stripped naked and having your dignity violated, and a constant barrage of waterboarding, he wouldn't be so relaxed about this.
Most people go crazy just being locked in a room alone for a few days. With the above-mentioned "enhancements", the process towards breaking someone down is sped up considerably.
