When people were asked whether they would want medical treatments to extend their lives by decades so they could live to be 120 or more, 56% of adult Americans aged 18 and over declined the offer. When asked how long they would like to live, 69% gave an answer of between 79 and 100 years. The median ideal age is 90 years, about 11 years longer than the current life expectancy of Americans.
