This is a pretty interesting article, and there's been a lot of positive research regarding coffee consumption in the past few years. I am a coffee fanatic, and hope that my three cups a day will lead me to a longer life. I have a lot of ideas for future directions of study regarding coffee: my primary interest is teasing the health impacts of espresso beans vs regular beans in varying roast states, if there are any such differences. Additionally, I wonder if there's any studies on the social impact of coffee consumption. I take most of my coffee alone, but I used to have a raucous coffee group a few years back, and it's well understood that social interaction is good for your health. I also wonder if there's any studies which examine the rates and contexts/reasons that people in different professions consume coffee. All of the lawyers/scientists/doctors/software engineers I know tend to always have a cup in hand-- especially the doctors.
