Leonid Gavrilov and Natalia Gavrilova are prominent bio-demographers who applied the principles of reliability theory (the study of the failure of industrial systems) to human biology.
Their theory explains two phenomena associated with aging – the Gompertz Law of exponential increase in mortality rates together with the late-life mortality plateau (where mortality rates seem to level out at very old ages).
