Nuclear fusion makes the stars shine,
Phototropism makes Ivy twine,
Rayleigh Scattering makes the sky blue,
Sexual hormones make me love you.

What's going on with this "love" thing that I keep hearing about these days? It sounds like a wonderful thing to have, but nobody seems to be able to tell me what it is! Whenever I ask my friends, they keep telling me that "it's hard to explain". How can everybody want something so badly when they can't even say what it is? And the songs, Oh the songs! It seems like musicians talk about nothing else! "Your love is like sunshine", can you be any more vague? Please, somebody, give me a straight answer, I beg of you!

After putting a lot of thought into it, I think I finally have an answer.
Love does not exist.

I'm not saying this as a rash young romantic who's had his heart broken for the first time, I'm being as rational as I can be.

If you believe W.D. Hamilton and Richard Dawkins' theory of the selfish gene, the only logical conclusion that can be reached (on the topic of love) is that love doesn't exist. When a mother dies to save her baby, is it because she loves it, or because she's protecting her genes' propagation? Nobody would die to save somebody else's baby, and why would you? If you die, you can no longer reproduce, so you become a genetic cul-de-sac. Would you die for your S.O.? I doubt it, it just doesn't make sense.
No, love doesn't have to make sense, that's what makes it love! What makes "love" so special that it's beyond the reach of logic?

My Mum always said that "children are an investment", and that parents will "protect their investment" (Momma always had a way of explainin' things so I could undustaynd them). My Dad always said that "the purpose of life is to reproduce". Perhaps it was those ideas that got me on the road to my current conclusion, perhaps I would believe in love if they weren't so honest blunt. It hardly matters now anyway.

I know this is an awful writeup, I have a strong feeling that this is going to end up in Node Heaven.
