This video is worth a watch.
A quote caught me as I watched it the first time. It comes in the first few minutes:
"Beauty and seduction are nature's tools for survival... because we protect what we fall in love with."
My dad sent it to me yesterday. You need to watch the whole thing.
Okay... P.S. It led me to this video, which just might be even better. (Sorry Dad, maybe you don't have to tell me if you look at this one.)
