I often get asked when I'm going to have a carrier of my DNA. My answer varies anywhere from "never" to "maybe some time in the future." The truth is I don't know. That's a big responsibility, for one thing. I don't have the time, the finances, or the space for a mini-me. Sure, sure, you say, but there's really never a good time for a baby, it just all seems to work out. Well, if I ever have one, I want to be as prepared as possible. Like, Boy Scout prepared.
That takes us on to the real issue here: I don't think my DNA needs replicating. First off, one me is enough for this planet. More than enough, really. Secondly, there's too many health issues in my family. Of babies and adults current and past, there's been one with Cerebral Palsy, jaundice, scoliosis, asthma, loss of visual acuity, heart trouble, cancer, skin troubles, bone disorders, developmental disorders...the list goes on. There's even some mental health to throw in there. Now, I'm sure that most families have something wrong with them somewhere, but several of these issues are too closely tied to my own DNA for my taste. I would be horrified to find that I had given birth to a human that will have to suffer. I would go ahead and do something more permanent to my inner factory, but, being as young as I am, I am a bit hesitant about making such a life-altering decision.
Really, I think it'd be great if we could spay/neuter some people. Sounds a bit harsh, I know, but I bet you could name at least 5 people off the top of your head that should not be replicating their DNA.
You're still thinking about it, aren't you? Ok, fine. I'll name 5: Ted Bundy, Kate Gosselin, Josef Stalin, Rudy Eugene, and probably Adolf Hitler, too. (I say "probably" because the man was a genius. Just a really cruel, evil genius. So yeah, let's just go with "should not procreate.")
I think it's also important to consider the world population. There's a lot of people out there. Seriously. I think it would be a better use of resources to adopt a child. Yes, that child could have health issues, too, but it's already born. My theoretical child doesn't even exist in real theory.
