More scientists agree that the key to polar bear survival lies in their innate ability to have fun. Ethologist Robert Fagan, professor at the University of Alaska, studied polar bears for 15 years and observed that ones who played more often throughout adulthood led longer and healthier lives, thus leaving behind more offspring.

Playful animals such as polar bears can stimulate their survival skills by keeping the brain active and healthy. This playful has attitude been favored by evolution and may be why some animals live longer, according to ABC News. Polar bears who exhibit a playful demeanor are more likely to try new ways to survive obstacles.

Stuart Brown told the news source that "play is one of the brain's best forms of exercise. [It] keeps minds and brains flexible." Brown went further on to say innocent "rough and tumble play" opens the brains to new ideas.

As symbols of the current global warming situation, polar bears are facing more challenges to their survival. Although polar bears live a solitary lifestyle, those who play with their siblings while they are cubs are more likely to survive into adulthood.
