Mental disorders are indirectly contagious – i.e. negative emotional and behavioral patterns that cause illness are transferred even to friends of people with disorders, a study in Finland involving 700,000 people has shown.

The data showed that having friends diagnosed with mental disorders in the 9th grade of secondary school increased the risk of developing mental disorders later in life, such as mood swings, anxiety and eating disorders, by up to 18%.

Worth looking into this. The idea of the Pennebaker method goes back to a paper of his in 1986 that details the health benefits (including mental) of expressive writing. Sounds a lot like the underlying idea of morning pages, though that has the connotation of clearing one's head versus health related benefits.

Compare/contrast the two methods.

Is there research underpinning morning pages?
