While doing my own workout this morning I listened to a podcast of The Splendid Table interview a high school student who had tested New York foods. (The sheep's milk cheese came from cows, she said, and the sturgeon caviar was paddle fish.) Genetic tests are now standard equipment in all kinds of crime-fighting, not just murder cases.
But we are no longer talking about cheap tests that can tell cows from sheep, or can identify a father or criminal suspect. We're talking about gathering all your genetic details, and asking you to act on them.
Some doctors are asking ethical questions about this, concerned patients will demand cures for diseases they do not yet have.
What does it mean when genetic testing becomes a mass market? As Stanford bioengineer Stephen Quake noted after having his test done, "It's all bad news." Genes don't show happiness or athleticism. The results of a test usually tell you what you're likely to die of, and we're all likely to die of something.
