"The study does not prove that the loss of a marriage causes health problems, only that the two are associated," when I read this then yes I agree that it could probably causes a health problem such as Depression but nothing more than that. It isn't like they can get cancer or some other health problem from being divorced. It is said that they will suffer from the lack of eating sleeping, socializing and exercising, but these are also simple symptoms of depression. There is one part that confuses me that they never fully explained. "While remarrying led to some improvement in health, the study showed that most married people who became single never fully recovered from the physical declines associated with marital loss." Where it says 'physical declines,' it doesn't give examples. What physical health problem could there be that was caused from divorce.
The paragraph where they actually experimented the stress level between married couples is quite interesting. If the stress levels are high then the wound from the suction device will take two days instead of one day for couples who are not stressed. If a marriage is going to a dead end then of course they should divorce since getting a divorce isn't always going to cause some sort of health issue. For some it can cause relief or even less stress by leaving their partner.
