A friend of mine recently got onto a train and found a group of four seats that were empty except for one woman who was sitting face down. She looked asleep and he looked forward to a quiet journey. As soon as he sat down, the woman lifted her head to reveal streaming, puffy eyes and started sneezing profusely. This happened a few weeks after swine flu first began to dominate the headlines but being English, he was bound to the socially awkward choice of staying in his seat for the sake of avoiding social awkwardness.
Many of us probably have similar stories. At a time when fears of a flu pandemic dominate the headlines, does an innocuous sneeze make people fear the worst? Perhaps, but a new study suggests that hearing someone else sneeze plays with our minds far beyond exaggerated worries about pandemics. They can make us more worried about completely unrelated threats like heart attacks, crime and accidents. They can even affect our political attitudes.
