This accounts for why June Brown is still with us.
She's smoked since she was 16 (77 years) BUT doesn't inhale. This was also true of the UK's "oldest smoker", Winnie Langley who died aged 102 in 2010.
Asides from that, Brown follows a diet, does Tibetan exercises every morning, only has the occasional drink, and takes 14 supplements/vitamins a day.
So not exactly the binge drinking, chain smoking coffin dodger we're often led to believe she is.
