One emphasis of my research has been on the question of how people spend their time. Time is the ultimate finite resource, or course, so the question of how people spend it would seem to be important.

There is research on the effects of 9/11, and you know, compared to the enormity of it, it didn't have a huge effect on people's mood. They were going about their business, mostly.

People's mood is really determined primarily by their genetic make-up and personality, and in the second place by their immediate context, and only in the third and fourth place by worries and concerns and other things like that.
