If you had to fight animals one on one, which ones do you think you could beat? I think most of us could crush rodents, cats and small dogs with ease...but where does the line start?
The only rule is that there are no weapons besides a tree that a human can climb up. Is there a type of dog you think you couldn't handle? What happens if it was you against a cow? How the fuck do you kill a cow with your bare hands?
Food for thought.
