I'm at 12.8% risk for venous thromboembolism and the average (for "men of European ethnicity") is 12.3%.
Surely the difference is below the noise level of whatever data were used to get these figures? I make it about 0.16 millibits of Kullback-Leibler divergence, and upwards of 10,000 data points to have any chance of seeing the difference experimentally.
As everyone here knows, it would be a stupid idea to switch from airplanes to cars out of safety/terrorism concerns: Cars are a much more risky means of transportation than airplanes. But what other major risks are there that many people systematically undervalue or are not even consciously aware of?
The same can be asked for chances.
