title: Getting Age of Visitor on Website
body: <p>I need to write some code that gets the gender and age of a visitor on my website without asking for permission to store them, just like Google Analytics. </p>
  
  <p>I have managed figure out a way of getting the users gender using by using the Facebook Graph API (gender does not require user permission). So now I am stuck on a way I could get the visitors age as I cannot use Facebook Graph API for this as it requires permission from the user to get. </p>
  
  <p>Any ideas? Thanks for reading.</p>
