Helmet Age

Hi All,
I'm getting back into riding after years off. What's the deal with helmet lifespan?
I've got an awesome Shoei XR1100 that still fits perfectly. I brought it new, never been dropped, been stored well in a cool dry cupboard in the helmet bag, been off the bike for around 7 years it hasn't had much use. It does have the SAI Global Australian Standard Silver and Red "tick" sticker.
Can't see any mention of the age of a helmet here:

Any thoughts?
Cheers.
