This is truly one of the toughest stuff I have seen so far on Youtube: Romanian Special Forces demonstration session. The guys holding the targets inches away from their heads must be having balls of steel, the shooter no less. http://www.youtube.com/watch?v=gabOzuSi7Ig&feature=related
@TheSuperSensation: Funny. It's true that every job has it's health hazards, even if your job is sitting on a chair in front of the computer, or protecting the president. There is also knowledge and technology to prevent this hazards, or at least, to diminish their effects. These health hazards are usually overlooked. I have seen many threads and posts around here about drinking, drugs, energy drinks, staying up and working 12/24, 14/24, 16/24 and more, and only a few in where the users were considering integrating an active lifestyle into their long term IM plans.
