People break down after a couple of hours. All the defenses go down and there's a kind of communication that if I spent 20 years in a living room with one of these people I would never never know as much about them as I do in that one day.
I do not want to go into its physical reasons: the construction of the human body is different from that of carnivorous animals. But man's intelligence is such that it can be utilised to defend any-thing he does whether right or wrong.
