In her article “Down Syndrome Dangers” from this month's World, Joni Eareckson Tada writes,

A person with Down syndrome may never understand how to keep up with the Joneses or how to get over his head in debt. He or she may never be clever enough to sneak behind his spouse’s back and look for an illicit affair (yes, men and women with Down syndrome do marry, and some of those marriages are honest-to-goodness models to neighbors and friends). They won’t be cunning enough to know how to cheat, weave lies, or how to stab a friend in the back. People with Down Syndrome may not have driver’s licenses, but then again, neither do I—and I get around quite well for a quadriplegic.
