About this audiobook

The book offers an integrated framework for understanding sarcopenia and frailty as the tip of the iceberg of systemic aging. It treats muscles, skeleton, sensory systems, and brain not as separate organs but as a single “muscle–bone–senses–brain” network, embedded in the continuum of connective tissue and governed by a supra-level of subjectivity — the human will. Drawing on the theory of functional systems and the principle of optimality, the authors show how age-related involution reshapes afferent synthesis, the acceptor of the result, and action programs, shifting the system from a developmental mode to a mode of “costly survival,” in which every basic act demands too much energy and meaning. We propose the concept of Wellspan — the span of life lived with preserved wholeness, autonomy, and capacity for participation, regardless of the presence of chronic disease. Aging is interpreted not as an accumulation of breakdowns but as a change in the rules for distributing resources and in the scripts by which life is governed. On this basis, the authors substantiate a new philosophy of treatment as the art of navigating a life trajectory, where movement, sleep, nutrition, and sensory support become instruments of volitional reprogramming of the epigenetic background. Special emphasis is placed on frailty as a spectrum of shifted functional systems that lay down “rust” along the contours of control, cementing the script of fading away. The practical tool offered is the protocol “Steps to Restore Connection and Meaning in Frailty,” aimed at rebuilding the map of reality and everyday participation. The book does not duplicate clinical guidelines; its task is to provide a tool for thinking: to lift familiar clinical material to the level of systemic logic, in which sarcopenia, osteoporosis, and cognitive slowing are considered interrelated manifestations of a single involutional program. This approach lays the groundwork for revising clinical strategies so that the final stretch of life remains a space of Wellspan, rather than merely a prolongation of biological existence.
