Average life expectancy would nudge up to about 85 for both sexes, he predicts, and — importantly — people would be sick for a shorter time before death. “The best that could happen is that if someone doesn’t die of cardiovascular disease, they die from Alzheimer’s.”

How would an increased life expectancy rate affect the world?
