I was having a think in the shower this morning (as you do), and had a thought pop into my head. It was kind of a cool thought. It led to a couple other cool thoughts. They suggest a character for a story, but I'm not quite sure yet what the story would be. I'm also pretty sure I don't have the chops to write either character.
The subject: Time travel. But not as you know it.
Time travel is, of course, a well-worn device in science fiction. It goes right back to one of the founding fathers, H. G. Wells. Most time travel works either discontinuously (you disappear from one time and appear in another, like Back to the Future or Terminator) or at exceptional speeds (like Wells' Time Machine). This allows the central character to leap to other eras, which is of course the interesting use of time travel.

But what if we approached it slightly differently. First, we accept Einstein's space-time construct, in which time is just a fourth dimension on top of height, width, and length. This implies that one can move along that axis if one can figure out how. Except, actually, we are all moving along that axis. We are all time travelers, but traveling in a fixed direction (in the direction of increasing entropy) and at a fixed rate of speed (one second per second).
