Will you cheat?

Or will your partner cheat?  A neuroeconomist presents a scientific test:

My recent appearance on the Dr. Phil show prodded me to develop some simple tests for infidelity that expose the impact of this soup of chemicals. While there is no perfect test for whether a man will cheat, I will give you a list of things to look at. Most are subtle and below our conscious awareness. If enough of these factors line up, it might be time to worry.

Let's see how we do here.

1.  Resting heart rate.  +1
2.  Testosterone.  +2
3.  Movie/kids/dogs +1
4.  Public flirt +1
5.  Family +1

It would appear I'm just below the chemical cheating threshold and am therefore a reliable marital bet.  Science said so.
