To suggest that a positive attitude equates to a longer lifespan is a gut punch to the 40,000+ men and women dying from metastatic breast cancer each and every year. Research, not attitude, prolongs lives. I have known too many men and women who have had a positive attitude and who died none the less from cancer.
Those of us with a terminal diagnosis frequently experience chronic pain and suffer dehabiliting impacts from treatment. I've personally endured over 35 rounds of chemotherapy, 60 rounds of radiotherapy, six years of hormonal therapy and five surgeries. Although the author would like to think that a positive attitude prolongs life, there is no data to show that.
