Terrifying Nanobots are Invading My Body!

My body has been overcome by hordes of nanobots bent on destroying my tissues! They are ruthlessly efficient. And there are so many of them; they are reproducing constantly. It's terrifying. They seem to be focusing their efforts on my upper respritory tract, tearing it apart one cell at a time. I can already feel the damage and its getting worse by the hour.

I have unleashed my own armies of defensive machines, but so far the battle is a stalemate at best. I can only hope that the tides will turn. Otherwise, my fate may be sealed. Killed by the tinyest of enemies!

Oh, yes, I think you better know my condition as 'a cold.'
