Let us stay married for the children; could anyone start with researching if a spying device in each and every home picked up that type of dialogue and look at long term quality of life outcomes for offspring, comparing to those parents who either never married or divorced for the sake of their personal mental health?

Is quality of life collected in any way (besides medical questionnaire)? Does factors such as income, debt, and number of children as an adult somehow align to quality of life interpretation? Would that be dependent on the beholder of the data outcome?
