The microscopic world is something that we, as big multi-cellular organisms, feel separated from. We see pictures off it through a microscope or as sterilized artistic representations made by medical-science illustrators, but it is not something we confront plain as day right before our eyes.

But the thing is, it is something that we literally all have met with at an extremely intimate level, it’s just that we don’t think about it now. Every single one of us existed as a single cell at one point in our lives, aware of the other cells around us and actively functioning to exist at a world at that level. We existed at ever level between that and who we are now.

I think that is a concept worth thought.
