What I would like to know, and haven&#x27;t heard talked about in any of these articles yet, is if it&#x27;s possible to substantially alter the genome of an already living creature.<p>This article touches on it briefly at the beginning, but doesn&#x27;t elaborate on the idea:<p>&gt; This means it’s possible to create genetically modified plants or animals of practically any species, as well as to modify the cells of adult organisms, including humans.<p>But so far, I&#x27;ve seen every article go to great lengths to avoid a very obvious question.  Aside from medical cures, is it possible to use this technology for cosmetic purposes?  Will I be able to change my eye color permanently?  Cure baldness in adult humans?  Alter metabolism?
