Accurate Study?

Today I volunteered for this research study for the UofA Business department. It turned out that one of the survey's was all about wieght loss, dieting, self-efficacy, and goals. I'm not sure if my survey is really that accurate seeing it is at the end of Lent and biggest loser. Any other time I'm not sure if I would have been so confident in my answers or look so good on paper. Oh well, I hope I didn't mess up their study. Oh, and I got $10 for doing it, so not so much a volunteer thing....
