Fit as a fiddle is a commonly used synonym for being in very good health. It is often used to describe the physical well-being of a person. This idiom is used when a person\u2019s health is analysed on the basis of their agility and energy.<\/p>\n\n\n\n
A person who is often seen as healthy and physically well-maintained is called fit as a fiddle<\/em>. Moreover, the phrase originated in reference to stringed musical instruments like Violin. Meanwhile, these instruments are often called fiddle and have to always be kept well-maintained or fit.\u00a0<\/p>\n\n\n\n Therefore, as a musical is always well-maintained, a person who is well-maintained is said to be fit as a fiddle<\/em>. This phrase was first used in written texts in 1616 by Haughton William in his book English-men for My Money.<\/p>\n\n\n\n
