Another Six-word Story

I thought of another six word story today. This one is a little more serious than most of the others I wrote yesterday, but I also think it may be the most fitting. It is a bit more of a story and these words, do, I think, tell my mine. I'm going to let it speak for itself, though, and not explain like I did with my last ones .. . because I do think that is mainly the  point.

Ran too steady on life's treadmill.

I like coming up with these. I got to thinking today: when I start trying to come up with a story in six words, I find that it is easy to think of a lot that are seven words, but not so much six. Also a little easier to come up with five, but not as easy as seven (or more), so I wonder . . . is the six word idea based on something a little bit scientific? Is it just the right amount of words to make it difficult enough to have to think a little harder, but not too few that you cannot do anything with it? Any rhyme or reason for why Smith Magazine picked six words and not seven or five or nine? I will have to look that up and see. I'm sure I'm not the first person to ask that question.
