I can attest that I have personally saved the lives of friends on two occasions thanks to good situational awareness, and have saved myself from serious injury or death many times more.

It is not my impression that I lead a very dangerous life.

These two statements seem contradictory to me. Maybe you ought to specify what you mean by "saved from death". If I consider crossing the street, notice an approaching car, and procede to not cross the street until the car has passed, did I just save myself from death? Describing the particular incidents and pointing out exactly how SA helped you to stay alive where others would have died would be much more convincing.
