there are people who are dedicated to the stunt profession. This guy in my film production class became very popular because he did the craziest stunts, everything from jumping through a glass window (real glass), to swinging on a vine off of a cliff (and landing face first into a huge boulder), to jumping into the back of an oncoming truck from another vehicle at a pretty high speed (unsuccessfully rolling off the back of the flatbed and onto the pavement- but he did finally get it on the 8th take, and a reduction in speed.)
This guy even let himself get punched in the face once. What did he have to say after all of this? "That was just like nothing..." Remember, this is just a college kid. Well, I guess it's all in who you know.
Oh Well...
