Well, that may be the case, and if it is, I find it sad in itself.
Most of these superlong models won´t die at 80 still sporting floor-length ponytails, anyway, if we allow us some realism.
But from 1997 on (when I went online), we have had such a supply of ever new incredibly gorgeous superlong haired beauties on the web that we just can´t complain or have to cry over one of them going short(er).
I remember very well, all too well, in fact, that before the days of the internet, we had to savour and save every little newspaper or magazine clipping with some waist-length woman, which was usually just once a year or even more seldom than that. Now we get to see dozens of knee-length models (and longer) every day. And we can download for free or buy as we wish pics and videos to enjoy at home a million times in HD.
These are good days for people like us.
