I know someone who keeps a "backup site" handy just in case something bad happens to the main site. Different content, same business, but intentionally not well positioned. Should it be needed, he will do a little work on it and soon thereafter it will be ranked high up. Since the age of the site is known to be an important factor, having a backup in the index allows the aging to occur. Therefore, should it be needed, its age should not be a factor.
