fit as a fiddle

In excellent health, in good working order. The proverbial likening of human good health to a fiddle dates from 1600 or earlier, but there is no completely convincing explanation of the analogy. It appeared in print in the early seventeenth century and was in John Ray’s proverb collection of 1678.

It was only in the nineteenth century that the meaning of physical fitness was attached to the expression, where it remains today.See also: fiddle, fit

Fleas have hard bodies flattened from side to side and piercing and sucking mouthparts. Their legs are powerful and adapted for fast movement and jumping, enabling them to find new hosts as well as to escape quickly the attempts of the hosts to remove them. The adults can survive away from a host for several weeks without eating. Flea eggs are usually laid in dirt or in the nest of the host; the larvae feed on organic material and the feces of adult fleas. Metamorphosismetamorphosis
