The Consequences of Medicine 2.0

Steve Friedman: Modernity has brought many wonderful things in terms of the successes of medicine 2.0, but it's also brought a lot of things that have increased our susceptibility to chronic diseases. He says there are many factors at work that have kept life span from increasing and behavioral changes have probably been really important. Friedman: Most traditional ways of thinking about risk look at a very short term, time horizon, five to 10 years. When you study things over relatively short durations that are lifelong diseases, it's very difficult to get meaningful answers.
