Complex medical procedures can seem to the layperson almost magical. We can snip out someone’s heart, put it into someone else’s body, and it starts beating. We can graft tissue and replace corneas. We can sustain heartbeats and blood pressure using complex machines, which loop the blood out of the body, oxygenate it, and feed it back in. These procedures come with great risk, but at least they are possible.
For most of human history, the things that killed us just killed us. Now, with the help of machines, doctors, and humans who give pieces of their bodies to complete strangers in death, we can live longer, healthier lives. As modern people, we exist not only as ourselves any longer, but as the interconnections between various humans and technologies.
