Audiophile demographics?


Why are there a disproportional number of male audiophiles?
Not sure if this is a silly question, but speaking for myself, I have never met a female audiophile.
I am sure they exist, but their scarcity begs the question as to why.
Is it merely that men have more of the "mine is bigger than yours" mentality, do men love gadgets and tools or is it something more sinister?

Far more guys are gearheads than are gals. 
Coincidentally, far more guys are into the gal in your avatar than are gearheads.
not just women but is there any audiophiles under 30
Women are smarter than men.
