Are you too old to be an audiophile?

DISCLAIMER: This is not meant to be offensive in anyway, just something I've always been curious about and thought it would make for some interesting responses.

One of the things about audiophiles I've always wondered is how they reconcile their age, and the scientific fact that their hearing isn't what it used to be, with their belief they can can hear all the nuances of high end gear, and even the cables. As we age we lose our ability to hear mainly in the higher frequencies. You know that high pitched sound older CRT televisions and some recessed lighting can make? No? Neither do my parents.
Thoughts?
