After the age of 35, the odds of Down Syndrome goes from being 1 in 1,300 to 1 out of 400. After the age of 45, it goes to being 1 in 100. THAT'S BAD!!! Those are solid statistics. It isn't subjective.
It has nothing to do with abortion. Statistically, after a woman reaches a certain age, bad things tend to happen. Anyone that wants to have children should do so while they are in their LATE teens to mid 20s anyway. As I said earlier, that's when folks are best equipped to handle it, both mentally and physically. I've known some people that have had children into their late 30s-early 40s that went well, but it's risky.... Not to mention, they are going to be old, and nodding off at their kid's high school graduation.
Downs syndrome is still a very low risk and it isn’t the end of the world to have a special needs child, is it?
