I'd just be a panda coz pandas get spoiled by zoos and whatnot. And they don't even need to do anything. They just sit down there and eat bamboo and sleep and they still look adorable.
I be a tapeworm. Floating in food all day all night and never knowing what is the winter weather like.
Bigbossh20, bald eagles only live around 30 years. There is an urban legend, however, that states that once an eagle is 40 its beak and talons bend out of shape. At this point in life, they would scale the tallest mountain and destroy their own beaks/talons and wait 150 days for them to grow back. Then they would be able to live another 40 years. But this is purely myth.
