You get information like: You have a 11% greater chance of developing disease X as compared to most people. That first line above sounds useful, right? But read on... Then you find out that most people have a 0.3% chance of getting disease X (3 tenths of 1 percent chance, for those who wonder if I've made a typo). So, instead of a 0.3% chance, you have a 0.333% chance. Big deal. The ancestry part is interesting. But if I had it to do over again, I might not do it, because by doing so I made some of my family members uncomfortable by revealing some of their private information without their consent.
