Well, say if I want to exercise my muscles. We go together to a gym, and I lift weights and train some muscles. One day, I feel, "Oh, there's a leaderboard in the gym. I want to get a perfect score." So instead of me, I send my robot to the gym with you. And the robot starts lifting weights. The robot can be humanized, look just like me, except, of course, it lifts a lot more weight! So I get a top score in the gym.
