OK I d like to suggest that this article should take brief notice of un designed consequences both good and bad and that a sentence two at most on what those consequences are should then be supported by full references including quotations Or in a footnote but personally I think the present system works well Tim makes a good point in that we should also take notice of the many anecdotes of a helmet saved my life Since the existence of many of these is not controversial perhaps we should just have a sentence describing them If we want a reference we could use though Tim and Linda might reasonably have further suggestions
