'chest-related' originates from the English word 'chest,' which refers to the front part of the body between the neck and the abdomen, and the suffix '-related,' indicating a connection or association.

The term 'chest' has been used in English since the Middle Ages, derived from the Old English 'cest,' meaning a box or coffer, and eventually came to refer to the human torso.

Initially, 'chest' referred to a storage box, but over time it evolved to describe the human torso, and 'chest-related' now refers to anything associated with this part of the body.
