On the flip side, we can’t touch, hold, and measure love; we can only feel it. We can feel it flowing and recognize when there’s a resistance to the flow; but how do we measure that in order to compare it to water or blood? How can we determine if it’s thicker than blood?

Of course, I’m being a little facetious here. The old adage isn’t about physical science at all. It’s about something that is philosophical and metaphysical in nature and, therefore, requires going deeper.
