* rise in sexual diseases, which are more likely by age
* BIRTH CONTROL PILLS, medications in general, and SPERMICIDAL CHEMICAL AGENTS on condoms, and rubber chickens!
that's funny, i've seen articles that suggest a very minimal increase in birth defects for older women, and that doctors encourage it. the graph y is obviously 10k to make the graph curve highly accentuated
3. Down syndrome has nothing to do with race, nationality, socioeconomic status, religion, or anything the mother or father did during pregnancy.
many if not most women drink, drinking is related to birth defects, the older the woman the more exposure
the same can be said of most of the * points above
most of the DNA multi-phase steps are performed in "making eggs" which are completed by puberty (pre-teen age) (this means only the last several phases - the "mass mitsiosis" at the time of pregnancy are involved)

----------------------------
is there a ABSOLUTELY MASSIVE RISE OVER JUST 10 YEARS because older women are more often becoming pregnant at older ages (women have long lived into 80's 90's, no change there)
But today MOST women over 40 on dating sites express they don't want children: and since the 80's there is "birth control". So the fact of there being more older babies i would call highly suspect.
that indicates chemicals introduces and more accessible to women in the 70's to present
