Life expectancy in the UK is on the increase, despite worries of rising obesity levels.
The good news has been credited to a decline in heart disease due to improving health care and less people smoking.
The figures came from analysing mortality rates over the last four decades.
But experts warn that we shouldn’t celebrate too quickly, as we are yet to see the impact on mortality rates of a new generation that carry obesity from their childhood into adulthood.
Professor Leon, from the London School of Hygiene and Tropical Medicine, told the BBC that "We are definitely seeing type-2 diabetes occurring more in teenagers due to obesity, but this is not immediately being translated into mortality rates."
Life expectancy figures for people in the UK now stand at 82.6 years for women, and 78.4 years for men.
