If you like to live on the edge, this job may be for you. Test subjects are also known as lab rats and their job is to act as guinea pigs for drugs and other products that have not yet been approved for use by humans. The drugs can have serious side effects and can adversely affect health and longevity. However it pays well, about $3000 per month and there is almost no work involved. It may not have the thrill of sky diving, but risk takers could find this job appealing.
