coolness n.
Synonyms: cool, composed, collected, unruffled, nonchalant, imperturbable, detached:
These adjectives indicate absence of excitement or discomposure in a person, especially in times of stress. Cool usually implies merely a high degree of self-control, but it may also indicate aloofness: "Keep strong, if possible. In any case, keep cool. Have unlimited patience" (B.H. Liddell Hart).
