If Jeff Mogil and Ron Melzack are right about genetics and pain, fifty years from now, generic Tylenol tablets will seem as quaint to us as a bottle of sarsaparilla tonic. Instead, we'll take our genotype ID bracely to the local genopharmacologist to order some bespoke pharmaceuticals. Or we may rise at four A.M. to meditate on the part of our nature that is painful and feel better for it. Along with social insurance, we'll carry geno-cards that list our predispositions: photosensitivity, osteoporosis, and poor response to codeine.
