Suppose you are volunteering with a public health agency in a state that has just passed a law that makes bicycle helmets mandatory for all riders. describe two ways you could determine whether the law is improving bike rider safety and public health

Transportation laws promoting safety precautions, such as the helmet law,  lead to an increase in public health. Legislation on speed limits, drunk driving are a few of the most obvious examples.  Wearing a helmet, without question, reduces a rider's risk of injury. However, Public education and infrastructure upgrades, protect riders considerably even before helmets come into the scene.   

The most common stereotypes could be that boys don't cryboys don't get emotional boys are never as mature as girlsboys are lazyetc.
