This week I read a wonderful article on the largest to-date study ever conducted on the health risks and benefits of coffee drinking. To my great relief the study strongly showed that even modest daily amounts of coffee over time dramatically reduces your risks of several diseases such as diabetes. Now, all good modelers know not to confuse correlation and causality and its possible that some other trait common to coffee drinkers is the real benefit. But I haven't had good health news in a while, so let me have this one, ok?
