Being Positive Isn't Bad, But - - -

"Many people like myself who are living with a chronic disease and a dying family member find that without an emphasis on the bright side of things, the negatives would be too overwhelming. However, I believe it is important to be careful with generalizations about positivity. As in the example above, saying that 'patients whose moods were overall more positive were 58 percent more likely to live at least another five years' is a misrepresentation of the data. Used as medical advice in popular media venues, such generalizations are bound to have social and cultural repercussions."
