What can I say? I'm a casualty magnet. In the past two years alone, I've dealt with seven or eight incidents as a first aider including a couple of RTAs and a major fire. I've done 21 resus attempts in more than 20 years as a first aider, with four of those being successful. I know one of those people survived long term, but I don't know about the other three. (Someone commented that that's a good success rate but what has to be remembered is that in all of those I was at hand when the people arrested so therefore had the best chance of success. Any competent first aider in the same circumstances would have had the same results.) Over and above being a casualty magnet, I think two reasons why I've dealt with so many incidents is that I do notice when people are in trouble and I do get stuck in. As you say, a lot of people don't - even when they have the skills.
