Wrinkly fingers from sitting in the bath for too long could well have a useful purpose, according to research from Newcastle University.
Wrinkles that form on skin after being in water improves grip on wet objects, scientists claim to have shown.
The study compared the results of people taking objects out of water with and without the prune-like skin formation.
"We have shown that wrinkled fingers give a better grip in wet conditions.
It could be working like treads on your car tyres which allow more of the tyre to be in contact with the road and gives you a better grip.
Going back in time, this wrinkling of our fingers in wet conditions could have helped with gathering food from wet vegetation or streams.
And as we see the effect in our toes too, this may have been an advantage as it may have meant our ancestors were able to get a better footing in the rain."
