Do you ever wonder, while watching a nature documentary, what it must feel like to be the prey who's being eaten while they're still alive? Do you think they feel pain? Perhaps they feel an overwhelming sense of purpose, well-being. To know that they're being of use? It's hard to know. But I think that's where this impulse originates. We all know at some point we will be overwhelmed and dragged under, we'll die. And I'm guessing it isn't an entirely unpleasant experience.#
