If the heart stops for more than two minutes, you have massive brain death. There are only two minutes between our conscious world and zero. That’s how fragile our consciousness is.

Gibb frames consciousness as a precarious biological phenomenon, hinging on uninterrupted circulation and oxygenation. By reducing the boundary between lived experience and oblivion to “two minutes,” he emphasizes how quickly the brain’s integrative functions can fail when the body’s basic systems falter. The remark reads less like a medical claim than an existential reflection: our sense of self, memory, and awareness—often treated as stable or even transcendent—may depend on fragile physical conditions. The quote thus invites humility about human control and permanence, and it implicitly underscores the urgency of life, health, and the fleeting nature of subjective experience.
