I have a friend with Down syndrome. I will call him Tim.

Tim probably does not know how unusual his birth was. In our enlightened society, 90% of children like Tim are shredded with a vacuum tube or slowly dismembered, one limb at a time, prior to their birth. All of this is done out of compassion, of course. By popular standards, Tim is neither beautiful nor smart, and as we all know, life is not worth living unless you are beautiful and smart.
