I've had many people recommend exercising because it releases endorphins, and while I do feel better for a while after exercising, I've found that I will still become tired later that day. Usually, when I run out of productive or fun things to do (or that I have any desire to do) I will instantly become tired. I feel as though most people watch a movie or TV when they become extremely bored. I, on the other hand, take naps. It's almost as if my brain is programmed to induce sleep when I've reach a point in the day where I have no responsibilities are things to look forward too.
