My thoughts were racing as I stepped out of the shower just a few minutes ago. I was thinking about how, scientifically speaking, we're all made of stardust. (Really!)

And if that's the case, we're all part of each other, right? All of you are part of me, and all of me is part of all of you. We all came from the same supernova cocktail of elements and chemicals and space debris, after all.

Maybe that's why it hurts so much to realize that some of us aren't so great as humans. And maybe death and disease scare us all so much because what if it eventually means the end of us?

Considering all of that though, it turns out that we're actually infinite. Sure, the planet may one day be torn asunder and wind up in rubble, and there may be no human beings left alive in the universe, but we will have become stardust yet again, floating around and just waiting to coalesce into something or someone else. Maybe we were something or someone else. Maybe we still are.

We are forever. And I think that's kinda neat.
