Your body changes atom by atom, but your sense of self endures as a pattern

A science article explains that while the body replaces most of its atoms over years (roughly 330 grams per day), personal identity persists not through fixed matter but through organized patterns: memories, neural connections, and continuing biological processes. Some components—like eye lens proteins, teeth, and certain neurons—last for decades, but overall continuity arises from how the body and mind maintain structure and memory, making the self a process rather than a static object.
