But the news changes over time and reports that were accurate when posted may quickly become old news. Though we may post follow-up reports, and may continue to provide access to the original report, as in an archive of news stories, for example, we do not go back and change the original report to reflect new developments. If you are looking for the most recent information on a given subject, and not the history of how the story unfolded, be sure you’re not looking at an out-of-date report.</p> <p> <strong>AGE RESTRICTION<br> </strong>You must be at least 13 years old to register on the Discovery Sites.
