Could I Be A Hero?

Today outside my work there was a horrible car accident, involving 3 vehicles. 2 cars and an S.U.V. The people in one of the cars and the S.U.V only had minor injuries, however the man in the 2nd car had a large gash on his head and was bleeding badly, as well was trapped in his vehicle. How do I know all this? well, I witnessed the accident from the window by which I sit at work, and I know the people who were actually on the sidewalk coming to work when it happened.

Now, I do know First-AID, and I'm a fairly strong guy, I'm not superman or a heavy duty power lifter, but I'm stronger than the average bloke. I don't faint at the sight of blood, and don't get squeamish easily. The question I'm asking myself is, had I been there, on the sidewalk when this happened, would I have been able to jump in there and help? Or would I have been in too much shock and just stood there frozen in panic?

I would like to think I'd get in there and help. I don't think I've ever really been in a situation like that where I would need to react instantly to help someone in danger. I guess I've sort of been lucky in that sense. I'm hoping that if that time ever did come where I had to help someone in need like that, I'd be able to move quickly and be smart about it.
