Recently established think-tank the International Longevity Centre UK has unveiled new research at its first annual conference as part of a move to raise its profile.
The body, set up last year to influence policy-makers and planners on ways to improve living conditions, wants to mirror its prominent position in the US.
Results of the survey, which involved 836 people in the UK, 865 in France and 853 in the US, were unveiled at the conference.
A national press PR campaign is being run on the back of the results.
The survey found that more than half of UK respondents, and nearly two-thirds of those in the US wanted to live at least as long as the average life expectancy, even if it meant some pain, compared with a third of those in France.
