Living longer: a BBC Breakfast special
One person in three born today will live to be a hundred years old. It's a striking statistic - but what does it mean for the health and quality of life for those of us who will live that long?
In a special series this week, BBC Breakfast is exploring the changing attitudes to old age, and what a society with a growing number of pensioners means for us all.
In part one of our Living Longer strand, Graham Satchell looks at the science behind why people are living longer - and meets some centenarians who reveal what it's like to reach that special milestone.
