 Another factor associated with disability—reduced lifespan—arguably has an adverse impact on well-being. Many disabilities, or their associated disease processes, result in lower-than-average life expectancy, though it is worth emphasizing that the relationship between disability and reduced lifespan is contingent, and so even if reduced lifespan necessarily reduces well-being, it would not follow that disability necessarily reduces well-being. Moreover, it is not clear that reduced lifespan necessarily reduces well-being. It is at least arguable that living to 80, with the last 5 years of one’s life in severe pain, does not yield more well-being than a life of 75 relatively painless years. And it is at least arguable that longer lives correlate with greater well-being because they enable one to pass through all of life’s stages—childhood, adolescence, young adulthood, middle age, and gradual aging—but that having passed through all of life’s stages, additional years yield small increases in well-being. Clearly, these are complicated issues that deserve more attention. We simply note that there is no straightforward inference to be drawn from disability’s correlation with reduced lifespan to disability’s having an adverse effect on well-being.
