I would be pretty interested in what all those researchers think of emotions. <br><br>Emotions are related to every situation and guide our behavior at all times. Even if that means that it triggers thoughts <br><br>I believe that we should include possible emotional states in all those studies about human psychology and behavior,(reply>), @Independent Installations your personal take has nothing to do with the validity of the statistics.,(reply>), @joe jones again if happier is material sure. How many wealthy people have a heathy marriage? How many have been destroyed by a bad divorce. The unexpected death of a loved one? The means to support addictions that are killing them, this one more for the ones who gain wealth suddenly but still quite common seeing the stars battling addictions.  The day ill agree that money can buy happiness is the day you can turn back time after getting the call at 2 am that your child just died in a car crash, or was killed in the service.
