Question

ive always wanted to know, and dont say something like, life, or women.

I mean like an object.

Answer 1

My pick is diamonds.  why if, diamonds are rare.   Why do  almost every women has at least one?  I saw on TV where this talking head said De Beers  ' or something like that) ration them to rich buyers to artificially  inflate prices.  To me jewelry is a waste of money even if women get a fine piece of rock, they wish for a bigger one.
