really think they are happy? you know, or not feeling stressed at work because they have no control over the work space, they have no sense of am i going to be here for the long-term and be able it take care of my family over the long-term? i don't know what the methodology of this particular study is, but i would wonder what is their class size that they're surveying. >> it will be interesting to see if there are differences in class. this is purely speculation. the methodology that they used in terms of obtaining the results. this wasn't sort of self-reporting how do you feel. they actually measured stress hormones to find where they were higher, and a lot of their participants were surprised to find that their stress hormones were higher at home. >> who were they measuring? i know the second shift is real. i iced to go home before i had kids, before you had kids, and we would slump down on the couch and maybe have a glass of wine and relax. now we might have that glass of wine and ob the couch, but we also have the kids all over us
