Curiosity killed the cat or care killed the cat idiom, meaning too much worry can cause burden or tension. This phrase was used by Ben Jonson in 1598, in his city comedy title, \u201cEvery Man in His Humour\u201d, and William Shakespeare also uses it in the late 16th century in his famous comedy work \u2018Much Ado About Nothing\u2019. This idiom is often used to alert someone for being too inquisitive about things that don\u2019t even concern them. Thus, this idiomatic expression means that excessive curiosity is not good as it would lead to negative repercussions. <\/p>\n\n\n\n
