Would You Take Part In A Paid Medical Experiment?

... if you were offered cash to partake in a medical experiment that involved taking pills and then providing an assessment of the effect the pills had on you would you do it?

... have you ever taken part in an experiment like that before?

... also, how would you react if you found out the government was secretly doing stuff to you for research purposes? stuff like hitting you with microwaves signals or putting chemicals in the drinking water?

... comments?
