I just got my test results back from 23andMe, a service that analyzes your DNA. I paid $100 for the service and agreed to a one year, $10/month subscription for updates on genetic research.
I’m impressed by the report they provided. It includes sections for disease risks (increased and decreased), carrier traits, responses to drugs, and traits (in the Traits section I learned that I’m “fast caffeine metabolizer” and a “likely sprinter”).
