Will be very _very_ interesting to see if the tech develops enough in my lifetime to where people can send in spit samples to a medical firm, have their genome processed and then the medical company can remove any genetic predispositions to certain defects, etc... You could then also (for a hefty price), choose to have different traits embedded in your embryo - different eye colors, hair types, jawline, etc.

I'm sure we'll eventually get to the point where you can go to a medical company, throw your spit into a machine and be able to check on/off boxes for desired traits, remove negative traits, etc. etc. and have a baby ready for you under accelerated growth in weeks, not months. For added comedy, have it delivered by drone - instead of a stork delivering your child, it could be Amazon!
