Lara, D.; Bisol, L.; Akiskal, H., et al: Validation of the “rule of three”, the “red sign” and temperament as behavioral markers of bipolar spectrum disorders in a large sample, in Journal of Affective Disorders, Vol. 183, September 2015, DOI: http://dx.doi.org/10.1016/j.jad.2015.04.046
"…29 markers were overexpressed in bipolar groups, … the most robust differences in those with bipolarity… were
≥3 religion changes,
cheating the partner regularly,
having ≥60 lifetime sexual partners,
speaking ≥3 foreign languages,
having ≥2 apparent tattoos,
Doing any of these things does not necessarily mean that one has bipolar. These are just behaviors seen in unusually high incidence in people who have bipolar.
