shuffle off this mortal coil

Etymology:

• Coil’ is an ancient word, commonly used centuries before Shakespeare, and spelt ‘coyle.’ It was a noun and referred, for want of a better way of expressing it, to a mess – a mixture of messy things such as noise, confusion, uncertainty, bustle and so on. We don’t use it like that anymore but most of Shakespeare’s audience would have received it in that way. https://nosweatshakespeare.com/quotes/famous/mortal-coil/
