OK, history lesson.
Humourism was a theory of human philosophy adopted by Greek and Roman philosophers & physicians, and stayed the most common view of the human body in Europe until some guys started actually cutting up dead people in the 19th century, and realised what was really going on.
There were four humours, melancolia, phlegma, cholera and sanguis, also known as black bile, phlegm, yellow bile and blood, & these dictated what kind of a person you would be. The idea was that everyone had them inside, and when they were perfectly balanced, then you were healthy.
So. In the fine words of wikipedia:
"The Sanguine temperament personality is fairly extroverted. People of a sanguine temperament tend to enjoy social gatherings and making new friends. They tend to be creative and often daydream. However, some alone time is crucial for those of this temperament. Sanguine can also mean very sensitive, compassionate and thoughtful. Sanguine personalities generally struggle with following tasks all the way through, are chronically late, and tend to be forgetful and sometimes a little sarcastic. Often, when pursuing a new hobby, interest is lost quickly when it ceases to be engaging or fun. They are very much people persons. They are talkative and not shy."
The moral of the story: that's me in a paragraph. So therefore, that's me in a blog name.
