Yes, dear suave, they haven't figured it out yet. And the reason is that there are not enough brilliant minds on this, and not enough of them, and in the end not enough money, and governments who do not contribute because they turn away from young people suffering in silence and asking for death because they cannot endure the pain. Some of the researchers, not the brilliant ones obviously, but some of them are even further behind than the doctors who have worked on trying to help patients for decades. There just are not enough brilliant minds on this.
