Who Should Use LifeLock?

I am wondering whether there are some people that are more at risk for identity theft than others. I have been hearing about identity theft a lot lately, and I have been trying to decide what I should do to try to prevent this from happening to me, but I am not sure how great the risk actually is to me. I think if there was a lot of risk I would probably sign up for a company like Lifelock so that if anything did happen I would be protected and have some help getting my life back in order again.
