A study published by the Indiana University School of Medicine found that people separated from their spouses have the lowest life expectancy of all cancer patients. "Sixty-five percent of married patients survived at least five years after a cancer diagnosis, compared with 57 percent of those who had never been married, 52 percent of the divorced patients and 47 percent of widowed patients. But only 45 percent of patients who were separated at the time of diagnosis survived five years." Thus, it can be concluded that cancer hates people in an order: separated, singles, the divorced, and then the widowed. Which makes sense, because this is the order in which healthy people feel bad for cancer people, with people feeling worst for rumpled widowers with young sons to the point where we can't even look at them. A companion study however, should be conducted to find the affects on life expectancy of carcinogenic persons' partners, as it could very well be that the cancer is battling and zapping the life power juice of healthy spousal tissue. A companion to the companion study should be conducted to find out if by this original (and since totally bastardized) immunological logic, twins unknowingly separated at birth where one twin is just diagnosed with cancer as the other dies of cancer, has the lowest life expectancy of them all.
