You don’t consciously notice the danger signs: they are too subtle. But your nose and brain do. The real reason you cant bear sitting next to some people.

The nose and brain sniff for trouble on people around us — in the form of illness and infection — and tell us when to avoid them, for fear of catching their illnesses.

So suggests emerging research by Mats Olsson, a professor of neuroscience at the prestigious Karolinska Institute in Sweden .

He has found that our noses tell us instinctively to avoid people who are in the earliest stages of an infection — even before they show any physical signs of illness.

In a study he led, published last year in the journal Proceedings of the National Academy of Sciences, 22 volunteers were injected with harmless bacteria that activated their immune systems as though they had caught a contagious bug.
