Listen to this 'Talk of the Nation' topic

My parents waited a long time to have kids, or, at least, that's how it seemed when my sister and I were growing up. My mom was just about to turn 31 when I was born, and I remember as a kid, when I'd talk with my classmates about my family, it almost always turned out that their parents were five or even ten years younger than mine*. Nowadays, as the magic 3-0 looms for me, I can't imagine anyone feeling 31 is an old age to start a family. Times, they have a-changed, and these days the ages that raise eyebrows are as much as 20 years older than that, or more. The decision to start a family in middle life is about more than simple medical viability — to you, how old is too old? Should teenagers have to make decisions about elder care for the parents? Or, does the wisdom acquired in a long life lend itself to excellent child-rearing? If this is a decision you've made, or are making, on what factors did your decision hinge?

*For the record, my parents have incredible genes — no one ever looked at them and thought, "Dang! Sarah's parents are some old farts!"
