Childhood Stress Leaves Genetic Scars

sciencehabit writes "Traumatic experiences in early life can leave emotional scars. But a new study suggests that violence in childhood may leave a genetic mark as well. Researchers have found that children who are physically abused and bullied tend to have shorter telomeres — structures at the tips of chromosomes whose shrinkage has been linked to aging and disease."

    A study (http://www.pnas.org/content/109/17/6490.full) was published in PNAS today showing how low-ranking monkeys have worse immune systems than high-ranking monkeys. (In monkey societies, 'high-ranking' is a euphemism for bully.) We've known for a long time that subordinate monkeys have worse health and live shorter lives in general than dominant monkeys, but this is one of the first studies that describe how this actually happens, genetically and physiologically.

    Unless it happens on school grounds. Then people turn a blind eye.

    Especially if other kids are doing it. Then the school administration gives their silent consent by doing nothing about it. Or worse, when it's physical abuse, they punish both the bully who attacked someone without provocation and the one who defended himself, just to add that element of mindfuck to existing injustice.

    I am thankful to have had parents who told me I would not be in trouble for legitimate self-defense even if the school system was far less reasonable. What I found was that if you knock out one of them, the rest tend to leave you alone, for the nature of a bully is to find a doormat who will not fight back. I believe the school officials who have no doubt studied child psychology and the like are also aware of this and understand the injustice they facilitate. It is not mere bureaucratic ignorance but some kind of desired effect, a sort of unwritten portion of the curriculum.

    People who can and will stand up for themselves, even when a price must be paid, are extremely undesirable to increasingly tyrannical governments. It's something they would discourage and it is not difficult to understand why. It's amazing how hard that is to accept for people who cannot comprehend that organizations, like individuals, can also be selfish and encourage only what is in their long-term interests.

    It's already known that stress can seem to accelerate aging. Ever see those pictures of presidents before a term, then after? 4 years passed for everybody else, but it looks like they aged 10 years.

    Sorry, but that opinion is not healthy. Abuse is abuse, but on occasion a parent (assuming they are actually parenting) will have limits tested beyond any other punishment. Normally, I see your type of comment from one of two kinds of people.

    1. Those that have no children so have no idea what parenting is.

    2. Parents who's children are monsters that have no respect for any authority. Generally the parents are either ashamed or afraid to take the kids out in public, or the children are so poorly behaved that people don't want them in public.

    Truth be told, I have spanked my son 2 times in his whole life. The first time he refused to stop what he was doing, refused any punishment (go to time out) and was doing something dangerous. The second time, he was a bit older. He refused punishment and took a swing at me.

    Now unlike when I was a kid and just got the shit kicked out of me with a belt, I explained to my kid on both occasions why I had to punish him and how we could not repeat those mistakes. He learned valuable lessons on both occasions. In my opinion, he learned valuable lessons from those occasions. He is going to be an adult soon, and one day may ask for advice when it comes to parenting. I really hope he remembers how he was raised or talks to me before he talks to someone like you.

    Parents need to learn there are other ways to handle discipline and yes, aside from being damaging in yet another known way - previous revelations including lower test scores and greater aggression from children who have been spanked, spanking is the lazy way out. There are more effective, responsible means.

    Timeouts for one, if done right and that is key, if done right, are absolutely better. Parents screw this one up by making them too long or delaying them. I for one always found a minute per year of age, given immediately at the time of the infraction regardless of where we were, done standing, done silent and done facing a wall, corner, tree, whatever was handy and followed with an explanation for the punishment and a directive for future behavior was very effective. So effective in fact I would find no need for their use within a couple weeks time. I had compliance.

    Now I'll admit these weren't my children - rather I was a nanny for a great many years, and parents tend to have to be around their children a bit more than I had to, so perhaps adjustments would be necessary to maintain effectiveness. Or other avenues explored. My point is simply that there are other ways and they can be much more effective, if done right.

    I went to primary school in the 60's and throught those 6yrs there was an girl in my level to whom nature had not been kind. ALL the other kids would yell "Allison's germs" and run away when she approached them in the schoolyard. It didn't help that her parents sent her to school with dirty clothes and oily hair, this just reinforced her status as the lepoar of the schoolyard. Sometimes she used their fear against them by delibertely following them, or steal their marbles by chasing them away. These 'attacks' often ended with her falling to the ground in tears. I'd like to say I befreinded her but I too saw the germs and not the Allison.

    Everyone remebers what happened to them in the schoolyard, it's much harder to remeber what you did to others. It's neither an remedy or an excuse for this behaviour but I beleive the Stanford prison experiments clearly demonstrated what old time religion had intuitvely known about human nature from day one, how did 'middle class' germans willingly become death camp gaurds, and why are kids so cruel? - Stable, strong societies survive, the "golden rule" found in most societies and religions combined with resrtricing the definition of "others" is a powerful stabalizing force, war against non-others is a powerful strenghtening force.
