@pleonasm - One of my friends recently took a CPR course and he told me he was the only one in the class who was doing it of his own accord. Everyone else in the class was getting certified because of their job.
It's great that so many jobs require people to learn CPR, but I was a bit saddened that more people weren't just taking it for their own interest. You never know when it will come in handy and you might be called on to use CPR whether you're a firefighter or a secretary.
I would much rather just keep myself up to date with the latest techniques every few years than risk being in a situation where I could have helped, but didn't know what to do. Particularly if children were involved.
