Smoking is one that comes to mind, for sure. It's not an injury, but it is related to public health. Wearing a seat belt is another one that comes to mind. There was policy on bike helmets, as well, on the east coast, if I'm correct. I'm not an expert in that area. I think there are policies, strategies and conversations that have been had in Canada previously that we can look to for motivation and hope, to see that change can be made and is possible.
