What's it like to turn 50 on May 14th, 2013? Only a percentage of 9 million can tell you from personal experience.
For you cybergeeks, how many of the 9 million with the 5-14 birthday are likely turning 50 in 2013? Is there a website that would do that math for me?
I get excited thinking that Mark Zuckerburg also had a birthday May 14th, and by the way, how old is he? In his 20s but maybe early 30s?
