I never had truley LONG hair as a teenager, but it was longer than most people thought appropriate. At the age of 17 I joined the Army where I stayed for the next 12 years, so no long hair there. All those years I kept telling myself that if I ever got out of the service, I would grow my hair down to my behind, but alas, it was not to happen. By the time I got out, my hair was making a strategic withdrawel from my head (otherwise known as a retreat).
Now I have no hair on the top of my head and so there is little point to growing it long in the back. <sob>
