I was reading this book as part of a work thing. There's a part of the first chapter that's describing the physiological response your body may have to a heated emotional discussion. That sounded just completely unreasonable to me. Yes we're pumped full of adrenaline but this sounds like hyperbole. Does this actually happen? Whenever I find myself in a very heated debate, I find I think clearly and am more sharp in my responses. Does this really happen?
