Christopher Hitchens then wrote of his experience, which lasted 17 seconds as you seen. That look on his face is very telling. Jason Linkon wrote of this on the Huff post , pay attention to this part of his piece.
They told me that when I activated the 'dead man's handle' - which is a simple process, you simply release something, let it go - I didn't do that. I practically, even though my hands were bound, I...as near as I could...I threw the thing out of my hand. I mean, I really wanted it to stop.
I could swear I shouted the code word, but I hadn't.
Everything completely goes on you when you're breathing water. You can't think about anything else.
It would be bad enough if you did have something. Suppose if they wanted to know where a relative of yours was...or a lover. You feel, "Well, I'm going to betray them now. Because this has to come to an end. I can't take this anymore." But what if you didn't have anything? What if you'd got the wrong guy? Then you would be in danger of losing your mind very quickly.
That last paragraph, I believe, is critical, especially considering the torture practices of the Chinese Communists - who we are now emulating - were designed to elicit false confessions from those who were tortured.
Attention should be paid to the aftermath of the experience as well, which Hitchens relates thusly:
As a result of this very brief experience, if I do anything that gets my heart rate up, and I'm breathing hard, panting, I have a slight panic sensation that I'm not going to be able to catch my breath again...lately I've been having this feeling of waking up feeling smothered, trying to push everything off my face.
