Full context:   A study (that later was questioned for nonplausible results and considered unsafe publication) was performed that tested the effect of psychosocial variables, in particular personality and stress, as risk factors for cancer and coronary heart disease (CHD). In this study, four personality types were recorded. Type 1 personality is cancer-prone, Type 2 is CHD-prone, Type 3 is alternating between behaviors characteristic of Types 1 and 2, and Type 4 is a healthy, autonomous type hypothesized to survive best. The data suggest that the Type 1 probands die mainly from cancer, type 2 from CHD, whereas Type 3 and especially Type 4 probands show a much lower death rate. Two additional types of personalities were measured Type 5 and Type 6. Type 5 is a rational anti-emotional type, which shows characteristics common to Type 1 and Type 2. Type 6 personality shows psychopathic tendencies and is prone to drug addiction and AIDS.
