Actually, yes it is. Depends on how much pressure is asserted. If it is only broken half way, then the nerve is severed and we become paralyzed. That is why I had said 'if done properly.' Also, this is a good reason why you should never allow a large snake to sit around your neck. It only takes a few pounds of pressure to break a human's neck and those larger/giant boids are VERY strong.
Just keep walking and ignore the monkeys...
