Studies suggest that some fraction of the decline of aging is self-inflicted, in the sense of being due to a lack of suitable exercise, gain of weight, smoking, and the like. While it isn’t possible to avoid growing old, more of the unpleasant portions of aging can be evaded than is thought to be the case by the public at large.

New research has shown that older people with very low heart disease risks also have very little frailty, raising the possibility that frailty could be prevented. The largest study of its kind found that even small reductions in risk factors helped to reduce frailty, as well as dementia, chronic pain, and other disabling conditions of old age. Many perceive frailty
