Thank you for writing this. I used to wonder how flies have such terrific reaction times and whip around the air with insane agility. And then I wondered if we are just seeing them in fast forward, due to the relatively slow clock in our heads. I imagined it was why they had such a short lifespan of just several days. And I imagined them seeing us as glacially moving statues—"man this guy hasn't moved in years!"

Reading your description of cells as moving imperceptibly fast only fills me more with this sense—that we are very slow moving giants, waiting on the billions of "years" of inner machinery time to tick us forward ever so slowly.
