The Liver Pump

The first liver pumps started to be implanted in the elderly in the mid-2040s. They weren't anything major; they just provided a continuous flow of blood, even when your heart stopped. If you weren't bleeding, you would continue to get enough oxygen to your brain to prevent damage for hours. The other organs also had no damage, even half a day after heart stoppage. Death had been pushed back further than ever before with one small device.

They also provided better blood flow to the heart and skin. People started looking and feeling younger with the implant. The version that came with the synthetic blood extended everything even more. It carried oxygen more efficiently and allowed breathing underwater. The bonus of keeping people from greying or blacking out in even the worst of maneuvers was just icing on the cake. The reported rise in IQ has been attributed to increased oxygen in the brain.

Addition pumps are in the works and may end as two smaller units and one large one positioned at the extremities to increase blood flow. The one in the groin would be the larger one and would increase the oxygenation of the legs without increasing the stress on the heart. The arm pumps reduced the load on the heart enough that most people had sub-30 BPM.

Endurance races began to have insane results. People sprinted the entire time and still were not out of breath at the end. Swimmers on the moon easily ran across the surface of the water in the freestyle events. In those where they had to use a specific style, they often were above the water scrambling across the surface more than underwater.

I can't wait to see what the future will bring to humans and sports.
