Anti-ageing guru Bryan Johnson claims organs age differently; his liver is 18, heart 37, and left ear 64. The science behind this remains under debate.
Doctors explain organ aging is influenced by genetics, lifestyle, and environmental stressors like pollution and diet.

The liver, despite its regenerative ability, can age prematurely from alcohol, obesity, and toxins. Proper care keeps it young.
Cognitive aging stems from genetics and stress, but mental stimulation and healthy diets can slow it down, say doctors.
Sarcopenia and osteoporosis naturally occur with age, but strength training and calcium help counteract these changes.

The heart's age is affected by diet, stress, and exercise. Arteriosclerosis stiffens arteries, but aerobic activity slows this.

Johnson's idea of reversing organ age sparks curiosity. Doctors argue function can mimic youth but true reversal is unproven.
Gene therapy, senolytics, and stem cell treatments show promise in mimicking youth-like states but need more research.
Caloric restriction, intermittent fasting, and regular exercise improve organ health, mimicking younger biological states.
