Why longevity experts are reading organs, not disease

Can your body’s hidden reserves of everyday strength be the key to living a longer, healthier life instead of mere disease management? That’s how ‘intrinsic capacity’ is quietly redefining conversations around longevity. The concept — introduced in 2015 by World Health Organisation (WHO) — tests how your organs and body systems are performing from the inside out: how briskly you move, how sharply you think, how clearly you see and hear, your emotional groundedness, and your overall biological energy to evaluate your true functional age.
