Stress causes direct aging of the arteries, and this increases blood pressure, driving it even higher. Elevated blood pressure causes the greatest acceleration of arterial aging. Research at Johns Hopkins Medical School indicated that people who had elevated blood pressure when exposed to mental "stress tests" (not just the physical treadmill stress tests normally used to detect heart strain) were more than twenty times more likely to have heart and arterial diseases.
Furthermore, individuals who had "hot" reactions -- those who were more likely to get agitated or frustrated by life events -- had twenty times the rate of arterial aging, as measured by the incidence of heart attacks and strokes, than people who had "cool" reactions. Other studies have shown that those who keep anger inside rather than expressing it outwardly (those who are stressed internally) have the greatest risk of aging from the stress.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
