What is the Origin of Physiological Function Rectangularization?

The term was conceptualized by demographers and biogerontologists to illustrate the ideal outcome of successful anti-aging and preventative health interventions. 'Rectangularization' is a graphical representation of the healthspan goal, contrasting with the traditional, sloped survival curve that reflects a long period of chronic decline. It is a key metric for evaluating the success of longevity protocols.

What is the Mechanism of Physiological Function Rectangularization?

Achieving this rectangularization relies on maintaining the integrity and responsiveness of core homeostatic systems, particularly the endocrine and immune systems, deep into old age. Precision hormonal interventions, for instance, prevent the cascading decline of anabolic signals that drive sarcopenia and immunosenescence. By proactively mitigating the molecular damage that underlies chronic disease, the body's functional reserve is preserved, allowing the individual to maintain peak physiological performance for a significantly extended duration.

Physiological Function Rectangularization

Meaning

A theoretical and clinical goal in longevity medicine that aims to extend the period of robust health and high-level physiological function, represented graphically as a rectangular survival curve. This concept signifies a compression of the period of chronic illness and frailty into a very short span at the end of a long life. It is the practical objective of healthspan optimization, ensuring a vibrant, high-quality existence for the vast majority of one’s lifespan.
