the way I see it is...
as women age, their hair tends to get shorter and shorter.
my mom had long hair my whole life, now its short
look at most grandmas.. they have short hair
So... you KNOW that later in life you are going to rock the short hair, not as a matter of choice at some point, but it will be thin (menopause will fuck your shit up).
So why not enjoy the long flowing locks while you can?
