optimism is healthy

the impact of the mind on your health is wildly underapprecited. I think many health problems are at root exacerbated by - if not caused by - psychological stress. It is not just our diet that is far divorced from what it should be, it is our psychological state. We are chronically stressed. Anyway typically, optimism is good for your immune system:

Optimism boosts the immune system

Feeling better about the future might help you feel better for real. In a new study, psychological scientists Suzanne Segerstrom of the University of Kentucky and Sandra Sephton of the University of Louisville studied how law students' expectations about the future affected their immune response. Their conclusions: Optimism may be good for your health.

Other studies have found that people who are optimistic about their health tend to do better. For example, people who are optimistic about heart transplant surgery recover better from that grueling operation. But it's not clear how optimism affects your health — or whether pessimism makes you less healthy.
