Ischemia
The word "ischemia" () is from Greek ἴσχαιμος "iskhaimos", "staunching blood" from ἴσχω "iskhο", "keep back, restrain" and αἷμα "haima", "blood".
The Phlegmatics
The Phlegmatics draw their name from the ancient four humors theory of the Greek doctor Hippocrates (460-370 BC), who believed certain human moods, emotions and behaviors were caused by body fluids (called "humors"): blood, yellow bile, black bile, and phlegm. A phlegmatic person is calm and unemotional. Phlegmatic means "pertaining to phlegm", corresponds to the season of winter (wet and cold), and connotes the element of water.
While phlegmatics are generally self-content and kind, their shy personality can often inhibit enthusiasm in others and make themselves lazy and resistant to change.
