No, I think it's a good thing to know and I think everyone should know very basic first aid. Just don't assume that because you've done the course you'll click into automatic response mode. I think what I am saying is that when you are an assigned first aider it is a huge responsibility - we are talking people's lives here. I don't think anything prepares you to deal with the big stuff - it's not like we're trained doctors and nurses and the possibility of cock ups is enormous. A three/five/seven day course is not sufficient to prepare one for the shock/emotion that inevitably follows. I would never volunteer to be a first aider again but in an emergency, of courses I would step in.
