The body is like an orchestra where trillions of cell-musicians play a symphony from a shared DNA score. Newton taught us to see the system as a whole — here, as long as each follows the notes, we are healthy. But with age, copies accumulate misprints, and individual musicians start improvising. The noise grows: the ensemble loses coherence — fewer and fewer cells keep to the common rhythm.

Scientists described this breakdown as the accumulation of disorder and built a model predicting the tipping point. When damage exceeds the capacity for repair, a sudden collapse of the program occurs — the orchestra finally disintegrates into cacophony. From that moment, aging becomes visible to the naked eye. Surprisingly, the mathematical toolkit for the model came from quantum mechanics: von Neumann developed it to describe the loss of quantum coherence, while Dirac laid the foundations of quantum information. Now these ideas explain the collapse of the biological orchestra.
