Beauty is anything that is difficult to obtain.

True?
I'm not sure, but I'd love to hear your thoughts. This is what I was thinking:
It used to be attractive to be large because it meant that you had enough $$ to eat. Now it is attractive to be thin since the least expensive food (both in terms of money and time expenditure) is sugary/greasy/calorie-laden crap. It's easy to be large now. It is difficult to be thin.
Blue eyes are stereotypically thought as an attractive eye color (although I don't know how true that is anymore) but the blue-eyed gene is recessive, i.e. difficult.
Are there other examples?

i'm not dead, just tired.
i have tons to write about and no energy to do it.
will write more later.
