23andMe's kit has already told one of our reporters that they have a genetic predisposition for Alzheimer's, Celiac, and depression. Armed with that information, they were able to follow up with a specialised physician in order to learn more and be proactive. In addition to providing insight into their health, they learned about their ancestral makeup (French and Russian) and genetic traits (light-colored eyes, among other things).

But both kits are a relatively inexpensive way to learn more about your background, and for a short time, they're cheaper than ever.
