If we can decide whether or not our children will be vacinated why can't we decide whether or not our children will be unhelmeted?
We have the choice to guard our children against diptheria, polio, tetanus and whooping cough but are deemed completely incapable of making the choice to guard our children against head injuries.
Does that mean "Big Helmet" is more persuasive than "Big Pharma"? - surely not!
Why should we trust our government to make the right decision for our children? - their track record isn't exemplary with regards to the nation's little ones.
