Why I Have Daughters

A book (to be released this fall) explains why Heather and I have three girls and just one boy. I've wondered about this, and considered different theories of our family's gender distribution: conception dates, I'm a born sprinter, and a number of other theories.

But after all of this, it turns out that we have more girls because we're beautiful! Hooray for us.
