Science is getting close to explaining those prune-like fingers and toes we all get when we sit in the bath too long.
Researchers from Newcastle University have shown that wet objects are easier to handle with wrinkled fingers than with dry ones.
They suggest the creases could have evolved in our ancestors as they gathered food from wet vegetation or streams.
Dr Tom Smulders, evolutionary biologist at Newcastle University, told Today programme presenter James Naughtie that wrinkly fingers "help us to get a slightly better grip".
