not on your life

No chance whatsoever

Not on your life is an emphatic refusal, stronger than a simple no.

It suggests the request is so unwelcome that compliance is unthinkable: Can I borrow your car for the weekend? Not on your life.

The phrase implies "not even if my life depended on it," though it's typically used for mundane refusals rather than life-or-death situations.
