The nature of pain (physical) is rather uninteresting. If you’re conscious you can bear it, if its unbearable then you’re probably not around to feel it anyway. Psychological pain, by contrast, is extremely interesting. People hurt each other all the time and the nature of pain differs each time. I’ve learnt recently, for example, that when I’m accused of overspending it results in a kind of blinding flash of pain in the middle of my forehead. However when the accusation is say – not doing enough around the house the pain is more of a traveling headache. This is interesting given that there is probably some connection, between what the mind/brain perceives as a grater insult and the amount of pain one feels. Does anyone know anymore about the subject?
