Longevity is likely to continue to increase at a slower rate as new gains become harder to achieve, a report said.
While many potential anti-ageing interventions have been explored, the report What is ageing? Can we delay it? From the Longevity Science Panel, examined both the ageing process itself and the ways in which longevity could be increased.
More people doing exercise, improved nutrition and diet, and increased effective use of drugs such as statins were all highlighted as ways in which Longevity could be increased.
At present there is no "anti-ageing pill" likely to suddenly appear as drugs currently being trialled cause unacceptable side effects, but have future potential.
Technologies such as regenerative medicine will play a role in increasing lifespan, but it is unlikely there will be a dramatic increase in life expectancy, or a rate of increase as fast as that seen in the last few decades.
Dame Karen Dunnell, chair of the Longevity Science Panel, said: "From this research we have been able to build up a picture of the latest developments in this area. The experts tended to agree on which possible factors are important in understanding the biology of ageing. However, they did not necessarily agree on which are the most important components of the ageing process, or on which interventions might have the greatest potential for extending lifespan.
"Our goal for this project was to produce a report about the complex processes involved in ageing. We wanted it to be accessible to a wide spectrum of readers, not just those involved in academic study."
Joseph Lu, director of longevity risk for Legal & General said: "This topic is important to us and wider society, because of the impact anti-ageing technology might have on life expectancy.
"For example, recent research has shown genetic engineering can extend life expectancy in mice by 20%*. If this was possible to apply to humans, the USA's National Institutes of Health suggests that this could be equivalent to increasing the life expectancy of babies born today by 16 years - so that they live to age 95, rather than currently age 79."
