It may be very hard to guide a fertilized egg to make a boy or a girl, but it is extremely hard, and takes a lot of chromosomes, to help create the foundations for their character.

They didn’t say that life would be easy.
I enjoyed your post. I wish there were more serious ones like these on the internet.
