Valuable enjoyment
Many animals and birds indulge in physically energetic activities that appear to be purely for fun and entertainment. We say they are playing.
It is common among mammals and birds, but we may also see it in fish, octopuses, turtles, and insects.
We mainly associate playing with babies, children and juveniles. After birth, we have a lot to learn and practice before we become independent and capable adults. Playing is a form of self-learning. It is a natural development of the Life Instinct to help us grow, become strong and stay robust (Chapter 4).
Playing is natural schooling. To make sure we play evolution has made it enjoyable. The reward centres of our brain create a pleasurable sensation when we play, so we play. Children fill their unoccupied periods with it.
As adults, it also helps to maintain our mental, physical and emotional faculties throughout our lives. No wonder playing has developed in many life forms.
