I like looking at these studies to figure out how they cooked the books.

They admit younger 1st birth mean more births and more birth means more stress, but they don't separate more birth from younger births and throw them all together, making it a pointless study. You can see how pointless it is really when you look at the final chart that applies known risk factors. There's a very weak correlation to age of first birth and a strong one with the known risk factors.

For the Daily Mail to come up with that head line is very missing leading and dishonest.
