I was asked at 10am by the Guardian to write about how stress is shown in the body, by 12pm, while I’m on deadline to finish the second edit of Nine Pints, by next month. So I was appropriately stressed while writing it. But my nose isn’t cold. Even so, interesting stuff about the thermal imaging. I’m surprised at the surprise that faces and noses would be cold: in stressful/dangerous situations, it’s well known that blood moves from parts of the body that need it less to parts that need it more.

Cold noses, damaged DNA and other ways stress messes with your body, here.

Here is the Guardian’s chosen image and caption. May the phrase “frosty snout” be used more frequently.
