How long can the brain go without oxygen?
At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable.
What would happen if you lived forever?
Immortality could undermine these values and beliefs, as life would become cheap and abundant, and death would become obsolete and avoidable. Immortality could also affect our sense of gratitude and responsibility for our lives, as we would not have to face the consequences or limits of our actions.

Could a brain live forever?
Nope. Like the rest of your body, your brain is made of cells. These cells are not immortal. They can and do die, and they don't divide.
What keeps the brain alive?
The brain is very delicate and is well protected by the skull. It is surrounded by a fluid called cerebrospinal fluid (CSF). The main functions of CSF are to protect the brain (it acts as a shock absorber), to carry nutrients to the brain and remove waste from it.

What happens if you stop breathing for 1 minute?
When we hold out breath for long durations, oxygen levels decrease and carbon dioxide accumulates in the body. That changes the concentration of free hydrogen ions, which makes these cells more excitable, leading to abnormal functions. For most people, it's safe to hold your breath for a minute or two.

Why can't we live forever?
Telomeres naturally shorten as cells divide, eventually reaching a critical length that triggers cell death. This natural limit on cell division plays a significant role in the aging process. While genetics plays a substantial role in determining our lifespan, environmental factors also contribute significantly.
