Are you constantly stressed? Did you grow up disadvantaged [no judgement here, I did], or maybe you had a nurturing household as a child? As it turns out, we can see it in your genes.
A new study out published in the Proceedings of the National Academy of Sciences, shows a strong link between the way you are raised and your genes. The study used telomere length as a marker of stress, then compared it to genetic and environmental cues.
