How often should one replace a helmet?

Morning all. I was just searching this topic when I came across the following link. Not sure if it has been posted before but thought, for anyone like myself who is asking the same question, I would post the link here:

Think I saw another one that also kicked off a discussion on where you use it a lot (ie exposed to lots of sunlight), that it would potentially deteriorate faster

To be honest, I had never even considered foam age as an issue. My problem tends to be something has worn out - usually the pads, then you can't get spares as the helmet is no longer a current model. I buys spare pads at around the time of purchase now.

If you ride a lot, once a year. If not, once every two years. UV rays harms the helmet which in turn looses it's protection ability.

If the study in the OP is right, then this would appear not to be the case.
