Can you imagine?
They are hoping to regrow hearts.
What if they figured out how to regrow a spine.
People like Christopher Reeves could walk again, without any help from John Kerry. ;-)
I really pray that all these inventions/discoveries make their way into the mainstream, and that they are affordable enough for the average person to have viable access to them. If so, then the world will really have broken through the final barrier ...that of the pathogen ...and we will be facing a future where we have the opportunity to have a veritable heaven on earth. Think of it ...someone with liver failure simply gets a new one, someone with a weakening heart receives a new one without having to be put on a waiting list, someone with degenerating eye tissue manages to have their sight saved, etc etc etc. I really pray that all these discoveries move from breaking news into everyday fact for everyday people.
