Early this week I went to the annual medical check-up. When reviewing my medical test results and figures, the doctor told me according to statistics based on my age, ethnicity and geographic residence, my probability of a heart-attack in the next 10 years is 3.1% vs. the group average of 3.4%. He said he was pleased with my result. I responded that my figure was only marginally better. He said with a grin, “You have already beat those that are dead by your age!”. Well, that is a survivorship bias here, nevertheless I found myself speechless upon the “encouragement” given by him :s
