    Mr. Jackson said, "There's a big football game on TV at half past eleven." After lunch, Mr. Jackson was sitting on the sofa. The game was nice and he hoped his team would get the gold medal. His five-year-old daughter Emma came in and put her hand on his face. "Oh, how cold your hands are!" the man said, watching the game. "Go and ask your mummy to warm them.

The end result is that when we walk, we use around 25% less energy than walking on all fours, and this way of getting around also totally eliminate (淘汰) the need for a tail.
