From Hidden Frontier
The Andorians are a humanoid species from the moon, Andor. They are one of the founding members of the United Federation of Planets. They are formed into various clans. They are a very proud race and some might say just as a proud as the Vulcans, but more prickly about it.
Andorians, as a species, do not handle depression well. There is a social stigma attached to the condition. Andorians suffering from depression often do not commit suicide, as it is referred to as "the Coward's Death" - it brings shame to the Andorian's clan. As a result, many such Andorians choose to die in a blaze of glory. (HF 2.08 "Coward's Death")
