"researchers estimated that in the Netherlands the health benefits of cycling are at least nine times greater than the hazards, with the average person who switches to cycling living 3-14 months longer, while potentially losing 0.8-40 days of life due to increased exposure to air pollution and an average of 5-9 days due to fatal traffic accidents."
