My far biggest experience with physical pain was getting big tattoo on the back, 4x4 hour sessions. (got some bones broken, but that's not the same level of pain, and body releases some calming stuff to bloodstream, so really not comparable). Every of those 4 hours, the experience of lying on my stomach, and having a pizza-cutter running through my back here & there. The most sensitive parts are around the spine (understandable) and on the sides of back (not really sure why). The goal is not to twitch or move much, so some sort of mental self-control is necessary. First +-2 hours were cca OK, but after that, even lower amount of pain, presented with high spikes and almost constantly ate away my willpower. After each session, I felt like a small baby, able to navigate back home and perform simple mental tasks, but severely worn off, and mentally weak. I understand this is just a glimpse from a distance to real torture, uncontrolled, when you know you can die from it, or end up disabled in most horrible weays for human being. But it works, to some degree, on some levels. If you want to break somebody, it is one of the ways. The question is, how usable will the individual be after breaking, and your goal (get info, instill fear, or just destroy human being).
