Washington - You don't need to actually see or smell something unpleasant to know it is disgusting, you only need to look at someone else's expression, according to research.

Writing in the October 30th issue of the journal Neuron, they said they saw the same brain activity in people who smelled a foul odour and in those looking at someone else smelling a foul odour.
