Sign up for the 23andMe Personal Genome Service ($400) and find out more about yourself (besides that you like when this happens). The service sends you a kit, you send back a saliva sample, and they use a special genotyping process to read nearly 600,000 data points on your genome. The result? A better understanding of your personal chemistry, including ancestry, family inheritance, and possible medical genetic dispositions. It's like having a super-accurate palm reader for your DNA.
