Research Subjects Wanted!!! "ECG responses to Helicopter Underwater Escape Training"

We are looking for 30 healthy men to participate in an experiment in our helicopter underwater escape trainer at Survival Systems Ltd in Dartmouth to be arranged between March 25th and April 6th, 2008.

If you are in a helicopter accident over water you will be flipped upside down and submerged. Therefore, we want to see what your heart rate and response is when you are inverted in our helicopter underwater escape trainer. You will be compensated for your time with $100 cash! For more details about the study please e-mail us at some@email.address

I can't help but think that there are very few people who would do this for $100 but wouldn't do it for free. For some reason, I immediately thought of this.
