People tend to perceive things in a logarithmic scale. This includes our perception of light brightness and sound frequency (was it also volume?). Maybe we also perceive time this way. That would make sense because recent events usually affect you more than older ones. Take a look at the following picture:
The events spread out so nicely that you can actually relate between too recent and too old. Comparing with the linear timeline below I admit the first picture better reflects my view of these events:
Since openoffice does not seem to do timelines, I hacked together a little perl script to make the images. You can get it here.
