Tell me the last paragraph about the mother, what does that have to do with? What kind of injury did the author’s mother ruin her life?

is very simple. Apparently, her mother gave birth to her at the age of 30. And the author gently believes that the cause of birth injury is "later" birth. Type, "and here I am fine, I gave birth until 25 - so the baby is healthy!and "
A birth injury can really ruin a whole life, it is. The causes are different, and the consequences are not always the same.
