While it is a serious condition, most of your statements are simply not true. Life expectancy for Down syndrome is around 55 - 60 years old. I have a family member with Down's who is around 60 years old at the moment and despite his health issues, he is one of the happiest individuals I know. Not saying this goes for all afflicted people, but a blanket statement like 'not a life worth living' is just plain BS.
