Has anyone ever tried medical testing for money?

I did in college and it paid pretty well for the weekend I submitted myself to testing. But I don't think it is worth it. For the last 10 years this guy who calls himself "Chuck" keeps following me around. He is in my bathroom mirror, in any kind of water, or in my windows watching me and imitating me. How does he do that?? "Chuck" loves to repeat my every action and even repeats the same things I say to him. Every so often, I'll see "Chuck" walking with my wife or putting his hands around her and it pisses me off! The craziest thing is that I think I know this guy from somewhere, but I don't know how or where?????

Don't do it unless your absolutely dying for money.

A friend of mine did it and he had a cyst in his nose for a couple of months. He couldn't properly breathe out of one nostril.
