Spaw (and anyone else who's interested) --

I don't know about anyone else, but I interpreted that line: "As only a woman's heart can know" as saying knowing in a way that is unique to a woman: i.e., not that only women can know such pain, but that being a woman (including the experience of childbirth, or simply the knowledge that you can have children, among other things), gives us a certain perspective of grief and lonlieness that men do not have.

Not that that perspective is richer or poorer or better or worse than a man's, just that it is a woman's perspective, and that it's not the same as a man's.

Oh, and on a slight tangent: as I understand it (and I could be mistaken, but I heard this in a radio interview with a cardiologist), a heart is slightly different than say, the muscles in our arms and legs in that there are neurons connected directly to it -- and that there are neurons also connected to our stomachs... makes me wonder if that is the subconscious origins of phrases like: "deciding with the heart" or "Gut decision"
