This reminds me of one of my favorite books, by Poul Anderson, "Boat of a Million Years". It follows the lives of 11 individuals whose DNS allows them to be immortal with respect to aging. They can still be injured just like anyone else. It starts around 300BC and goes into the future. Much of human history is portrayed through the eyed of those who don't age. It also goes into what happens to the world when this gift is finally shared with everyone.

If you are being half-way serious. Try downloading Space Monger. On Windows at least it does a Great! job of helping you understand what the "dark data" on every hard disk actually is. Always amazes me how much of it is under the Windows directory.
