People are so impressed now with predictive models based on any kind of correlation. Like: "we predict what kind of wine you will like based on your favorite candy bar" or "how long you'll live based on what you eat for breakfast". Only thing is, it's hard to find any two variables that aren't correlated, to some degree. Actuarial mathematicians have been doing this long enough to know how limited the "predictive power" really is.
