Five-year helmet lifespan?

I personally think Duke had previous unrelated damage.

There is a lot of legal crap going on right now. While at bike week, one of the helmet retailers told me of a story of an older man and woman on a Harley when somebody ran a light and T Boned them. The man dies and the wife lives. The insurance company--did not say who's or what company--was fighting the case because neither were wearing a DOT approved helmet. They were wearing cheap novelty helmets and because the state did not require helmets at all. However, because they WERE wearing A helmet and it was NOT approved, they were saying they did not have to pay. Not sure of the outcome or just where it was---I was eavesdropping as I was buying my own helmet. After dealing with reptiles at GEICO in an auto injury in which my wife was a passenger, it sounds very familiar. They are now looking for every reason to deny a claim.
