Well, a treatment at least. It may come from people with Down syndrome, who have significantly less chance of developing cancer. It seems to be related to the way their genes express themselves in the development of blood vessels. Of course, its a long path from knowing how something works to being able to recreate the effect ourselves. Ironic that they might be providing us with a way to immeasurably improve our lives while we're killing them in mass.
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
