The gap between male and female life expectancy is closing and men could catch up by 2030, according to an adviser for the Office for National Statistics.
Prof Les Mayhew said the difference between the sexes peaked at nearly six years in the 1970s.
Life expectancy is going up all round, but the rates for men are increasing faster.
Plummeting smoking rates in men are thought to explain a lot of the change.
Prof Mayhew, a professor of statistics at Cass Business School, analysed life expectancy data in England and Wales. He was working out how long 30-year-olds could expect to live.
