When something gives you a rush of adrenaline it hypes you up you get super excited, sometimes it triggers your flight or fight instinct if your in a dangerous situation. (Hope this helps)
The answer, I think, has to do with the fact that this book is what we call a classic. Its enduring value in my view lies not so much in its political theories as in the way it discloses or articulates a particular way of looking at the world. The Prince shows us what the world looks like when viewed from a strictly demoralized perspective. I think that’s what the fascination and also the scandal is all about.
An unintentional injury is an injury inflicted upon a person without the suspect's purpose of a motive whereas intentional is the opposite and the suspect has a motive behind the injury.
Intentional: Mark decides to get revenge on Matt for flirting with his girlfriend. He picks up the golf putter at their nightly outting of Go-Go Golf and smacks the metal end down on Matt's collarbone. The force cracks his collarbone.
Unintentional: Maria is driving but is slightly under the influence. She sees a man crossing the road in the middle of the night and attempts to swerve out of the way. She clips his calves and heels, causing burns/lacerations on his legs, but he is otherwise okay.
