Ok, this is something I can chime in on as I have quite of bit of knowledge and training. The "styrofoam" mentioned above is called expanded polystyrene ( please forgive if I misspelled that). Over time it does degrade from a number of factors. Main one is the moisture from the air and your head sweating. Even though you air it out and wash the inner comfort liner, moisture seeps in and causes it to degrade. Also the outer shell degrades from the uv light. Five years is what retailers like me recommend so that we can keep customers alive long enough to sell those new helmets. It's about protecting you, the end user. Could a helmet protect you longer than that? Possibly. But it could also catastrophically fail when you need it most. I hate hearing about riders who pass away from injuries caused by insufficient or outdated gear. Please don't allow yourself to be added to that statistic. Buy the best helmet you can afford, wear it for every ride, and ride safely. If you do that, it increases your chances of survival considerably while on your bike.
