As a 30+ year firefighter I can honestly say that there are more dangerous jobs out there, but...
Most of the 'more dangerous jobs' have defined situations and significant planning that go into each act, effort or attempt. Most have significantly higher pay for each one of them. Most are more dangerous in a clear and specific way - ergo, falling from a building, and realistic and practical planning and intervention can be used. And most do not deal with the single most dangerous component in the world - people; typically people who are on 'the other side of the picture.' Criminals, people who are prepared to hurt others without any consideration for who or where they are.
If you're willing to stand 'in the line of fire,' in a unplanned, unrehearsed, unpredictable situation as the intervention between someone who wants to kill someone else and the intended victim without any consideration for the effects...then you should be one of us.
If not, then consider our sacrifices for you.
