Video: Drinking coffee for longer life

There's encouraging news for the world's coffee addicts. US researchers have found that people who live longer tend to be people who enjoy a caffeinated cup or two - as long as you stay away from the milk and sugar.

The study from the US government's Cancer Institute studied more than 400,000 people, and found drinkers of two to three cups a day had a 10 - 13 per cent chance of outlasting those who eschew the brew.

But as the good news percolated through the bean scene, cafe dwellers said they would have continued with their daily fix - even if the study's had given the opposite results.
