Never had any interest in having children, and the more I've learned about the state of the world the happier I am with my choices.

Yes. I'd rather be the "eccentric uncle QuentinCallaghan" to my siblings' kids than a father to any kid in a world like this. I'm so used to having my own independence and freedom, and I'm a hedonist to some extent. Also having kids would require a relationship, and the Yellowstone volcano erupting is more likely than that.

God no. I can't imagine a more horrific punishment than to be childless.

I wish we had more than the two we have, but my wife and I started late. My daughter (12) sometimes asks how many children she could realistically have... a good sign that she hasn't been tainted by whatever mental illness it is that the "childfree" people have.
