This text introduces process–constraint biology, a framework that shifts the focus of life sciences from cataloging parts to understanding how living systems maintain viability. It argues that life is not a machine executing a genetic program but an ongoing activity sustained by dynamic boundaries that prevent thermodynamic collapse. Instead of seeking perfection or optimization, organisms prioritize staying within feasible margins of energy, time, and space. The author explains that disease and aging are not caused by broken components but by the erosion of these essential constraints. By reframing biological entities as stabilized process bundles, the text suggests that medicine should focus on restoring systemic coherence rather than targeting isolated molecules. Ultimately, life is defined as the disciplined avoidance of non-viable states through the continuous management of limits.
