Correlation is not causation. But yeah, exercising is healthy. Who knew?

  In the UK context people cycle in cities. London, in particular, has a serious problem of pollution. This research answers questions about whether benefits from cycling outweigh harms from pollution (yes) or harms from road traffic accidents (yes).

    they don't really. Keep in mind this is only for constant cycling...mixed cycling and commutes is actually worse than constant walking for cardio vascular incidence and mortality, and only is better overall for cancer incidence. You're actually more at risk to die if you constantly walk than if you are sedentary (1.03 to 1.0) and more likely to die from cancer if so (1.10 to 1.0). If you only occasionally walk though, you are less likely to die of cancer than if you always walk. I think honestly there are issues here. And why would cycling affect cancer of all things, and only constant cycling?

      > why would cycling affect cancer of all things Obesity is linked to about 20% of cancer cases. People who cycle tend not to be obese.
