Average age of audiophiles

Hi everyone,
I'm curious about the average age of audiophiles. One of the owner of an audio store told me that he has a lot of customers in their mid 20s that buy really high end gear. Personnally, I would think the average age is above 40. I really can't confirm since I'm the I don't know anyody else crazy enough (or passionnate) to get a sound system as expensive as a car...

Also, how old were you when you started this hobby.

As far as I'm concerned, I'm 26 years old. I got interested in this hobby when I was around 17...

Thanks everyone...
