I had a job a while back watching people on Workers Comp. I video taped and caught a lot of people working on vehicles, carrying groceries, working on their houses lifting and doing other activities that they said they couldn't do like stand, sit or walk, for long periods of time, they had to pay back WC. So if you do go just watch yourself, don't do the things you claimed you can't. By the way it's not a good job long hours stuck in a car, following people around it's back breaking and stressful. Then you have to testify in court against them.
