Actually, Michael, if I remember the story dad has told, I think those were pretty close to the exact words my grandfather used to define love:

Love is a chemical imbalance

Of course a chemical imbalance isn't necessarily bad. If there were no shifts back and forth between the different brain chemicals, we wouldn't feel anything at all...

I seem to remember walking being discribed as: losing your balance and catching it again befoere you fall.

So maybe we need imbalance in our lives in order to move forward.

And speaking of falling and love... I think it was Bucky Fuller who said that Gravity=Love.

That may be the connection right there...
