There was an article in our local paper about a study in which the older the child's father is, the higher the chance of a child having autism. I am just curious, what age was your father when you were born?
I left the options wide open for the under 30 bracket due to the study in the paper wording that the risk increases as the fathers start getting up in age. I figured anything under 30 wouldn't be considered "upper age limits of fatherhood". Sorry about that.
