More than any other condition, being diagnosed with dementia led participants to reduce the amount of time they’d want to live, with 89 percent saying it would definitely affect them. But having to live with chronic pain came in a close second at 85 percent, followed by being a burden to society at 71 percent and loneliness at 66 percent. A slight majority, 56 percent, said they would prefer shorter lives if falling into poverty. Among married participants, 62 percent said the death of one’s spouse would reduce their preferred life expectancy.
