Look at the cancer mortality. The 3 sigma bar is completely off to the left of the control line. In other words, everyone who cycles to work, will benefit from reduced cancer rates, with no exception. Even in the worst case scenerio, you would still derive a 20% reduction of cancer risk. It cannot get clearer than this. If this was a drug it would be a blockbuster drug.
