According to a recent UCLA study, one of the reasons women typically live longer than men is because of the different way in which they cope with stress.
When the body is stressed it triggers a hormone called oxytocin. This fast hormone flush rather predictably causes the "fight or flight" response in men. However, in women, high estrogen levels can dull the hormone’s effects and instead produce a different reaction, something that can be thought of as a "tend or befriend" response.
In other words, rather than metaphorically or literally engaging in combat or becoming terror-struck and high-tailing it away from perceived danger/stressors as a man more predictably does, a woman’s response to stress is more often informed by the urge to cultivate social ties. Details of the study suggest that this less confrontational response may be responsible for a lifetime of lower blood pressure, thus reducing the overall risk of stress-induced disease.
