where does the term dead end come from
Dead end (street) The expression cul-de-sac comes from French, where it originally meant "bottom of the sack".[44] It was first used in English in anatomy (since 1738). It was used for dead-end streets since 1800 in English (since the 14th century in French).[45] The often heard erroneous folk etymology "arse/ass [buttocks] of the sack" is based on the modern meaning of cul in French, Catalan, and Occitan, but cul doesn't have that meaning in cul-de-sac, which is still used to refer to dead ends in modern French although the terms impasse and voie sans issue are more common in modern French.
Death by natural causes A death by natural causes, as recorded by coroners and on death certificates and associated documents, is one that is primarily attributed to an illness or an internal malfunction of the body not directly influenced by external forces. Contrary to the statement before, everything is natural at some point. For example, a person dying from complications from influenza (an infection) or a heart attack (an internal body malfunction) or sudden heart failure would be listed as having died from natural causes. Health departments discourage listing old age as the cause of death because doing so does not benefit public health or medical research.[1] Old age is not a scientifically recognized cause of death; there is always a more direct cause,[citation needed] although it may be unknown in certain cases and could be one of a number of aging-associated diseases.
