I was just wondering, due to a non-valentine's day radio commercial for our local heart hospital, how did the heart become the symbol of love? Our heart has nothing to do with why/how we love. You could say "I love you because i can't live without you, just like you can live without a heart". But you can't live without a liver either. I've never seen a card that says "I (liver) you". There's that "cute little heart shape", but that's not even close to what a real heart looks like. Could probably draw a cute shape for just about any organ (except maybe intestines ). That "funny feeling you get" when you're around someone you love is more like a fluttery stomache than a feeling in your "heart area". *shrugs* so why this icon?
