Oh, what a great question!
Ever since I was very little I've wanted to be a bird!!! To soar above the lakes, valleys and trees. So easy, it would be, to fly from your enemies

I could go away from the cold, always living where it's warm and my home would be in a green canopy with a soft-down bed.
If not a bird then I'd be an ocean fish-- having --what is it?... 3 times more space to wonder around in than if I lived on the land.. and a fish is kind of like a bird that soars through the water over valleys, caves and coral!
it's fun to daydream....
