matters of life and death

Stakes couldn't higher

Matters of life and death are situations where survival or mortality hangs in the balance—decisions about medical treatment, wartime choices, emergency responses.

The phrase often appears in exaggerated form for emphasis: Calm down, it's not a matter of life and death.

Something treated as a matter of life and death receives the utmost seriousness, whether literally or hyperbolically.
