Old Helmets

The thread reminding us to wear our helmets got me thinking about old helmets.  How do you convince friends and loved ones to replace their aging helmets?

Mrs. gearboy and I went to a friend's house recently after doing a charity ride. They heard us talking about how much fun we have riding, and I offered to overhaul the bikes they had sitting the garage gathering dust and cobwebs (a 1970's  Ross and 1980's schwinn). When we got together a couple of weeks later, they initially showed up without their helmets, so the husband ran home to get them.  The helmets were at least 12-13 years old! What really shocked me was the wife is a doctor, who is also extremely cautious about pretty much EVERYTHING (as in she was appalled that we would eat wild berries without fear of cryptosporidia, and also made her husband undergo a series of blood and radiology tests because she thought he looked a little jaundiced - which turned out to have been from his recent eye exam where they gave him the yellow dye), thought nothing of riding around the local park without a helmet AT ALL, let alone an antique.

I gave them my usual lectures about riding with a helmet, and keeping things in good working order, which I guess worked since they did buy new ones later that week. But I have seen my sister-in-law's family doing the same thing. I suppose I should be happy they know enough to actually OWN and WEAR helmets, but I worry that they are having a false sense of security, and that if they get injured, they will actually stop wearing helmets because "they don't work".
