It's normal to live as a cyborg these days, the body wears out the brain is capable of near immortality. The new bodies are similar to organic ones however, in all the ways that matter. The cyborgs made great crew for the new spacecrafts too, after all, Earth has a head-count maximum that nature can support. Those of us who choose to live on this way have a moral obligation to become such inter-galactic protectors and conservationists.
When I put on my reading glasses I am a cyborg of sorts. So, relax, we give you a new arm with a robot hand, so what? You're still all human.
The cyborgs take their energy from sunlight and water directly from the air. Other than mineral supplements one a year or so they are good to go. We even grow their bodies in an environmentally friendly way. Plus, we only take the finest people, the kindest and most loving souls - the heroes, the good role models.
