If you’ve only got one job to do then you’d better do it, no matter what obstacles get in your way. Like 20 odd runners for example. This cameraman at the World Athletics Championships was so engrossed in the event he was filming that he didn’t notice that he’d wandered onto the main running track.
Spectators watched open-mouthed as the oblivious cameraman stood on the track, back to the oncoming runners. As the gap closed, witnesses could only watch helpless wondering what was going to happen.
