Death is a numbers game, and now the odds of dying within the next 10 years can be determined by a simple fitness test. In this case your mortality is associated with how close you get to your maximum heart rate while working out on a treadmill. The closer you get when doing simple exercise for a set amount of time, the sooner you'll die. Yikes. But don't try this at home because the test surely has a bunch of control factors that would need to be replicated in the lab setting. Perhaps the bigger picture is that these types of findings are an indication of a sea change in medical research—playing the data game. Proponents of applying the kind of data science used in finance to healthcare say that quantitative analysis can improve prevention and treatments. What do you think?
