Aging is a natural process that every living being experiences – growing old, accumulating cellular damage , and eventually passing away. The science of immortality challenges this inevitability, exploring whether aging can be slowed , halted, or even reversed. What was once speculative is now becoming a measurable scientific frontier , with real progress being made. Researchers are increasingly uncovering the molecular and cellular processes that drive aging. By understanding how DNA damage , protein misfolding , cellular senescence , and metabolic decline contribute to tissue and organ deterioration, scientists aim to intervene at the root causes of aging using experimental models . This approach could extend lifespan and dramatically improve quality of life , allowing humans to remain active, healthy, and mentally sharp far beyond current expectations. Cutting-edge therapies , such as telomere restoration , the removal o...
