Why a Facebook app wants your saliva

Did you know that your saliva, or spit as some might call it, can actually tell a lot about you? Hidden inside your saliva are tons of clues not only about your current health but also your genetic background as well. Now there's a new Facebook app that seeks to unlock much of this information. But like so many privacy concerns about Facebook, you might be wary about where that information goes and who could have access to it.

This new Facebook app says it can help you prevent disease, learn your ancestry, make you healthy and much more. All it asks in return is a hundred bucks and your saliva. This takes information tracking to the next level, but you might want to do it anyway.

This new Facebook app is actually an interface and communication service for a research project called Genes for Good, and it seems really interesting.

Your "spit kit" will be sent to the University of Michigan, where researchers will "screen the volunteers’ DNA to try to discover new links between certain genetic variants, health, and disease." The Facebook app is also a giant questionnaire where volunteers will enter in basic health information like age, weight, exercise regimen (if any) and other habits.
