What do you mean by horseplay?

Researchers discovered something interesting from watching young horses – called foals – at play: Foals that frolicked in the fields were more likely to survive to their first birthday. That must mean such “purposeless activity” plays some role in an animal’s survival. One theory, tested on lab rats, showed that rodents allowed to play were less stressed. (Rats that wrestle make chirping sounds that might be the rodent equivalent of gut-busting laughter.) Rats raised with playmates and fun objects developed bigger brains than rats that grew up in empty, boring cages. Just goes to show: Goofing off is good for you!
