In recent years, scientists have claimed that '60 is the new 40', mostly in response to our ageing population and research into changing attitudes on what it means to be 'old'. In 2000, the average life expectancy in the UK was 77 but in 2020, this rose to 81.
In 2022, “middle age” isn't what you might think—now 40 to 50, middle age (in theory) is older than ever before—and everyone's choosing their own path as we live longer lives.
