The musings on the random and tragic nature of life remind us of how little we know – and control. But it reminded me of the marketing of a step toward more control: how good are the DNA products? My daughter’s friend, visiting for Thanksgiving, sent her spit to 23andme. The results included a genetic tendency toward weight-related diseases, which led her to a diet and gym membership. Not surprisingly, it linked her with her mother, but also with a cousin neither she nor her mother knew existed. They met, looked each other over, compared notes: they were cousins.
Anyway, she sat in our living room flipping through her smart phone (it gives monthly updates); she was vulnerable to diabetes but less so to Parkinson’s. Genetic weaknesses are becoming obvious as we near retirement; unfortunately, we learn our vulnerabilities at every office visit.
Still, has anyone done this or similar ones? How accurate, how useful, and how much does this (or do others) add to the cloud-knowledge of genes & disease? (Other friends used a different site, but learned what human history would say – that they were both from England and before that Africa.)
Of course, whether it is worth the money or not, whether it is accurate or not, ignores the big question: does such knowledge lead us to believe we have an autonomy still not – never will be – ours? Will knowing more of “who we are” mislead or arm us?
