Mothers seemed happier back when I was a kid then today. Today they tend to scream about everything and I believe it's because like the article says they do not have a support group. The support group helps raise the kids and teach the mom bad habits like screaming do not work and a good slap will change children's attitude better. It also lets the kids know the mom has a network of others watching their behavior and if they do something someone will inform their parents and they watch their own behavior to avoid being punished like when I was a kid. Hell if a neighbor told my father I did anything my ass was going to have pain that night when he found out without a doubt. Now parents are weak and try to be friends and not parents, parents teach life skills, friends have fun and let you fuck up without correcting your actions for future success in life. So mothers that are older by this test are likely not raising their kids properly and their kids cause them to lose sleep and to be stressed out constantly, simple logic show us this. That is why single moms "welfare hoes" look older than moms in a good marriage with a close family.
