“It’s possible, one researcher says, that when people experience early-life stress “it actually changes something about them biologically.” Stress may influence how genes get switched on or off, for instance, or may initiate some other physiological effects.”

Now isn’t that interesting. I don’t really recall too much early life being stressful from my perspective. Though I can see where others would say that moving practically every year such that I went to 9 schools in 12 years might be stressful. My family was a tight knit group and my parents – especially my dad – made everything a fun adventure.
