Is this news to anyone? Older parents = higher risk of down syndrome. It has been known for a long time

Increasing risk with age has been known for decades.
According to the article it goes from a 0.1% chance to a 0.6% chance if *both* parents are over 35. Under a percent, still not that big of a deal, nobody should let that alone deter them from having kids.
They have a very, very low likelihood. It just happens to be higher than a very, very, very low likelihoo
