Americans have an anomalously high death rate due to injury, notably automobile accidents, that significantly drives life expectancy down. It is an adverse consequence of driving far more miles on average than people in any other country. Most Americans know someone who died in an auto accident.

An American that drives relatively few miles over their life changes their life expectancy to be one of the highest in the world. It is a high impact lifestyle choice that I made a decision to adopt many years ago in part for this very reason.
