The body continued running in the polished steel corridor, a corridor without doors and windows and without any hint of how far above and below the local planet's surface it was, if indeed it was connected with a planet. The corridor had a competition mixture of gases, gravity, temporature and pressure, and so on, and as the body had been running, lights turned on and then off so the body was at the center of a moving swathe of rather clinical light.

The life of the abandoned body slowly ebbed away, and the lights abruptly turned off.
It would be a while before a robot would come to clean it up and prepare the corridor for other uses.
"And without further ado," another mind announced, "I would like to introduce the researcher who broke the record for a running body by more than 594789.34 microseconds.
