Contrary to what the LBS and helmet manufacturers may recommend, I read somewhere that helmets do not need to be replaced every five years*. The materials don't degrade or stiffen with age, or at least not enough to matter.
*Applies to helmets that have not been crashed and styrofoam helmets with a hard outer shell. Foam helmets with a fabric only covering (such as those made in the '80's) should be tossed out.
