<p>I am conducting a research project, and need to know how to accurately test stress level on a large group of people. Anyone know how to do this?</p>
<p>some guy in my school did a test where he swabbed people's mouths w/ a q-tip of something. From what i understand, when you're under stress a hormone/enzyme/ gets released in your mouth and it's easily detectable. He tested people before and after a big test to see what the stress levels were.</p>
<p>I suggest doing some google research</p>
