"There's strong science showing that having a transcendent purpose helps you in changing your behaviors, in changing your life, but it is also good for your health.

[Researchers] found that people who had a weak purpose or no purpose in life were 2.4 times more likely to develop Alzheimer's disease than people who had a strong purpose in life. People with a strong purpose have been shown to live longer, to be less likely to get heart attacks and less likely to get a stroke."
