Holding my last breath...

Why is it that when you sink... it's always an imperative to rise again? ...to reach out, break through the surface and retake ...breath? What's really the point though? What is it inside ourselves that keeps us up? Why can't we just slip downward... lay on the bottom? And why is it that the only thing that can drag us down... is ourselves? Most people never manage to rise any higher... never walk on the waves... most just bottom out... for good... let go. Do they know something I don't? *looks up from below the surface* *sighs* ... I guess I let myself drag me down again... *will be up in a while*
