For the best part of two centuries people's life expectancy has been improving at a pretty rapid and consistent rate.
In the 1840s people did not live much past 40 on average. But then improvements in nutrition, hygiene, housing and sanitation during the Victorian period meant by the early 1900s life expectancy was approaching 60.
As the 20th Century progressed, with the exception of the war years, further gains were made with the introduction of universal health care and childhood immunisations.
From the 1970s onwards, medical advances in the care of stroke and heart attack patients in particular, saw big strides continue to be made
So much so that by the start of the 21st Century, life expectancy at birth had reached 80 for women and 75 for men.
And so it continued, with an extra year of life being added every four years or so.
But then it suddenly stopped - or rather rapidly slowed. The turning point was 2011.
