Data rich

Have a play with Wolfram Alpha if the day becomes tedious. It's a new search engine specialising in data enquiries, though most of the results have an American bias. Through it, I learned that I've been alive 21051 days. 116,873 people in the United States are called Bill. Most of them are 50, or 62. 0.11% of the American population have the surname Rogers. Found via Lifehacker.
