“The stress on the system moves the machinery to put down or not put down epigenetic markers.” Jirtle, an epigenetics researcher at North Carolina State University who was not involved in the study. “It’s either the stress of war or the malnutrition of war or both,” said Randy L. These epigenetic changes are inherited by later generations, setting diseases in motion. Crowding was extreme-each man was said to have had a grave’s worth of square footage to himself-and deaths from diarrhea and scurvy were common.īecause the study authors controlled for other factors that might have influenced the sons’ longevity, like socioeconomic status and the quality of the parents’ marriages, they believe this effect on mortality is working through epigenetics, or the process by which genes are switched on and off. The effects on longevity showed up for the sons of men who were imprisoned in 18, when conditions in POW camps were especially bad.

I can, however, write the perfect email to get myself out of a scrape, or find a way to stop thinking about why I didn’t get some plaudit or another. At the same time, I can’t do anything about the fact that the Holocaust happened, so I don’t want to spend time thinking about its effects on my cortisol levels. I am, of course, grateful that my life is easier than the lives of my relatives-Jewish and otherwise-who survived World War II. Of course you’re anxious, she seems to say you’re Jewish!
