‘Close the window or I’ll get a stiff neck and a cold’.

‘Don’t go to bed with wet hair or you’ll get a cold’.

‘Put on something warm so you don’t catch a cold’.

Since I am recovering from a common cold, these and other pieces of everyday wisdom have been circulating in my thick head. I have heard them from ostensibly intelligent people after swimming in the Black Sea when the water was a ‘chilly’ 25 degrees, from people who have imbibed them with their mother’s milk and regurgitate them unthinkingly, from my many wives and fruits of my loins at every conceivable opportunity. And I love trotting them out with an ironic twist whenever the chance arises.

But what’s interesting about this one is how useless dry, rational, scientific ‘facts’ are. No matter how often some specialist tells us that you don’t catch from a chill, from wet hair, from not wearing a scarf, people simply keep telling the same grand old story. No matter how regularly you come across explanations that viruses may enter your body from water droplets, from door handles, from touching someone who has the virus, it makes no difference – ‘don’t get a chill or you’ll catch a cold’ is as safe as ever.

At this quotidian level, it reflects the power of myths, legends, beliefs – and a bloody good thing it is too. So next time someone opens a window for fresh air in winter, tell them, ‘shut that pneumonia hole or I’ll get a stiff neck …’
