"You are one miniscule piece of a never-ending cycle. In fact, you're not even a piece. You're just a holder for billions and billions of other pieces. Whether that's organic components, living organisms inside your body, bacteria or whatever it is, you're just part of the soup of the universe, so just try to enjoy what's good about it."

The 4th sort of creatures... which moved through the 3 former sorts, were incredibly small, and so small in my eye that I judged, that if 100 of them lay [stretched out] one by another, they would not equal the length of a grain of course Sand; and according to this estimate, ten hundred thousand of them could not equal the dimensions of a grain of such course Sand. There was discover'd by me a fifth sort, which had near the thickness of the former, but they were almost twice as long. The first time bacteria were observed.
