Quantum immortality, with its seeming plausibility, may instill a sense of assurance in one’s continued existence. Nevertheless, amidst this perception of certainty, it is crucial to remain cognizant of the potential for enduring permanent damage to both the brain and body.

The prospect of evading death does not equate to an invulnerability against harm. While your existence may persist indefinitely, it is essential to acknowledge that the absence of mortality does not grant immunity from the possibility of sustaining injuries that could result in enduring consequences. Hence, while the concept of quantum immortality may offer a glimmer of hope for an eternal lifespan, it is vital to recognize that such an existence could still be marred by significant impairments to both physical and cognitive faculties.
