Replying to Is this worth it?

There's a study going on out here in Denver at the University hospital that i'm thinking of participating in. HEre's the deal with it all. It's a 19 day study, 6 of the days you must stay at the University clinic where the study is being conducted but you can walk around the facility and whatnot, but 10 of the days are spent directly in bed; no getting up at all. They put your bed up at a 30 degree angle 3 times a day so you can eat and the rest of the time you lay there flat, but you can roll around and lay on your side or whatever. They're testing a new drug that supposedly keeps muscles from weakening for people with illness that can't really do anything until they are better. So here's the thing that makes me want to do it, they pay you $4,225 for those 19 days of study cash. so my question is do you think it's worth it because i think I may do it.
