Cryonics involves

Cryonics involves

• A. Freezing the body or brain after death hoping for future revival; no proof it can ever work.
• B. A form of digital immortality.
• C. A method of caloric restriction.
• D. Relocating memory into a computer

Answer: (A)

Cryonics is the practice of preserving a body or brain at very low temperatures after death with the hope that future science can restore life. The essential point is that revival is hypothetical and not proven to be possible today, making it speculative rather than proven. Cryonics aims to slow or stop physical decay by freezing (often with cryoprotectants to prevent ice damage), but no method exists to bring someone back yet. This idea is different from digital immortality, which would mean uploading or storing a person’s mind in a computer. It’s also not about caloric restriction, which is a diet strategy to extend lifespan, or about moving memories into a computer, which is memory transfer.
