I've participated in (paid) computer marketing research sessions where they put you alone in a dark room and display a bunch of print ads for PC products up on a screen. Then they track the movement of your eyes to see which part of the ad attracted your attention the most. Then they ask you a bunch of questions about how the ad made you "feel". I guess this is the same application but taken to the consumer level. I think it will only be a matter of time before this implemented on web sites using all those built-in web cams.

Dr. Andrew Weil talked about this herb in his recent book Healthy Aging. It's a very good adaptogen, and I take it every day.
