This is utter insanity:<p>&gt; Liao would accomplish this height reduction through pre-implantation diagnosis, a screening test used to determine whether genetic or chromosomal disorders are present in developing embryos before they are inserted into mothers through in vitro procedures. While height would be somewhat trickier to test than most hereditary diseases—it is controlled by 697 genetic variants, in contrast to the single variant of a hereditary disease like cystic fibrosis—Liao views this as a mere “technical problem.”<p>&gt; Once science works out the kinks, he says, parents could screen for tallness just like they do now for disease.<p>He proposes aborting perfectly healthy embryos because they might grow up to be taller than he thinks people ought to be.  I suppose it would implicitly require that all pregnancies be initiated through IVF, as well.  What is this guy, the inverse of Khan Noonian Singh?<p>I suggest that Mr. Hendriks, &quot;a 6&quot; 4’ [sic] Dutchman,&quot; lead by example.
