Do exceptionally successful investors tend to live longer, or is this mostly selection bias?

I noticed something while reading about some of the most successful investors in history. Many investors with exceptionally strong investment records seem to have lived unusually long lives — for example Warren Buffett, George Soros, Edward Thorp, Charlie Munger, John Templeton, Walter Schloss, Philip Fisher, and Irving Kahn. This made me curious whether there is any real statistical association between exceptional investment performance and longevity. I am not suggesting that investment skill causes people to live longer. There are several obvious alternative explanations. Successful investors tend to be wealthy, may have better access to healthcare, and there could also be survivorship or selection bias. So my question is simply: Is there a reasonable statistical way to test whether investors with unusually strong investment performance tend to live longer than comparable people? For example, could we take a broad sample of professional investors, measure their investment performance, and compare their longevity with people of similar age, wealth, and professional background? Or would selection and survivorship effects make this relationship too difficult to estimate reliably? I'm mainly asking out of curiosity about how a statistician would approach this question.
