PICTURE THIS

WhaT your reaction to certain pictures reveals about your health HOW steep do you think this hill is?

The thinner you are, the less steep you will judge it, say researchers at Colorado State University. Fatter people will see it as steeper.

In a study published in 2016 they also found that overweight and older people both judge objects in the distance as being further away. This may be a defence mechanism the body uses to protect people from over-exerting themselves.

However, the downside of this, says lead researcher Professor Jessica Witt, is that this might also make exercising seem harder, putting off some larger people.
