A、Play can find your inner child. B、Play can help go against the rules. C、Play can bring greater achievement. D、Play is instinct

Play is very important for humans from birth to death. Play is not meant to be just for children. It is a form of freedom and connection that can tap into your creativity, and can allow you the chance to find your inner child, and the inner child of others. I have collected the top four benefits of play here.
    Play can stimulate you to think differently. It can go against all the rules and change the same old boring way of doing things. Walt Disney was devoted to play, and his willingness to oppose the common wisdom changed the world of entertainment. The next time you’re stuck in a fixed and boring way of life, pull out a box of colored pencils, modeling clay, glue and scissors, and invite your inner child out, and break free. You’ll be amazed that the way you’re thinking shifts to new worlds of discovery.
    Playing can bring greater joy into your life. What do you think the world would be like if every human spends time each day in play? I bet just asking you this question has brought a smile to your face-Play creates laughter, joy, entertainment and a feeling of inner peace. Starting today, try to get 30 minutes each day to engage in some form of play, and watch your joy factor rise.
    Play is known to reduce stress. Studies show that as humans, play is part of our nature. We have the need to play because it is instinctive and basic to human existence. With regular play, our problem solving and adaptive abilities will be in much better shape to handle this complex world. And we’re much more likely to choose healthy answer to challenging situations as they arise. It creates laughter and freedom that can instantly reduce stress, and add a feeling of relaxation to our daily living.
    Play can stimulate the imagination, curiosity and creativity. Research shows that play is both a hands-on and minds-on learning process. It produces a deeper, more meaningful understanding of the world and its possibilities. We begin giving meaning to life through story-making and playing out various possible situations.
