I am writing this again because yelp lost the original this company has contacted me over and over again promising a small fee if you. Qualify for their study. They ask too many question prior to disqualifying you. I wonder what they do with the masses of data for which I have never been paid. It seems to me that they could first asking innocuous questions like age, income etc before putting you through a health quiz. I have asked not to be contacted but they have ignored me. People should be more suspicious of people on the phone. It is knit worth the $2
