Facebook has made it pretty much effortless for even casual friends to remember your birthday. If you're looking for something more than a casual "Happy Birthday," though, check out You're Getting Old. You can see the facts about your own age, as well as some trivia about events occurring in your lifetime.

You can also set this up for your friend, using their Birthday and name, since the app gives you a unique link you can share with them. The app doesn't force you to sign in with Facebook or any other social networking account, and you can just use the web link to share the information.

What's Good: Adds a nice touch to Birthday wishes, doesn't require social network credentials to share.

What Sucks: It's not a site you have cause to go to all the time, so you're going to have to remember.

Buy it?: If you're looking to add a nice touch to your Facebook or Twitter Birthday greeting, check out You're Getting Old.
