Some anti-aging interventions don’t have age-dependent effects.

Researchers publishing in Nature Communications have determined that interventions that extend lifespan in mice may not have significant effects on the processes of aging.
Improvement is not the same as slowing decline
The researchers begin this paper by noting that previous studies have outlined a broad variety of dietary, environmental, and genetic factors that are associated with lifespan [1]. The researchers contend that this fact has had an influence on modern models of aging, including the Hallmarks of Aging. However, lifespan is often controlled by specific pathologies of old age. It is possible for an intervention to extend lifespan by preventing specific causes of death while having no real effect on any of the various aspects of aging.
