If your site's copy asks that question, one of the first things I should see after submitting my birthday is, indeed, my age after 1,000,000 seconds. Seeing a list of everything I could be <i>besides</i> 1,000,000 seconds old confused the heck out of me. :)<p>That said, pretty cute. I like it. You could make a cute viral Facebook app out of something like this (though maybe with less nerdy milestones).
