How fast can you ride a bike? Can you reach a speed of 44 km/h? And I do not mean downhill. If you can, that's great. Can you also do it for 180 kilometers after you have swum a distance of 3.8 kilometers?
Scientists once trained a chimpanzee in a cage to hit a lever. As a reward the chimpanzee was given a capsule to eat. The scientists gradually increased the number of times the chimp had to hit the lever to obtain a single capsule.
