Imagine a future where death is no longer inevitable. Experts predict that with advancements in technology, humans might be able to live indefinitely within the next 40 to 100 years. Several areas of research are driving this possibility: 1. Android Bodies Scientists are working on connecting human brains to external devices, potentially allowing people to control android bodies. This technology could enable minds to be uploaded to digital platforms, giving humans a new, potentially immortal form. 2. 3D-Printed Organs and Limbs Bioprinting is becoming a reality, with scientists successfully creating functional organs and limbs. This technology could allow for the replacement of worn-out body parts, significantly extending human lifespan. 3. Cryogenic Freezing Some organizations are already offering cryopreservation services, freezing human bodies in the hope that future technology can revive them. While still speculative, research in this area continues to advance. 4. Virtu...
