G,C,&D was surprisingly easy to read and understand. I did skip over some of the scientific jargon, but learned a lot and got hope from this very promising avenue toward curing or at least managing some of today's killer diseases. Sickle cell trait interested me because my grandson was born with it, even though no member of my family fits any of the ethnic groups mentioned. I learned to make sure he always gets plenty of water, to be especially careful about exercising and high elevations. That's news we can use.
Mr. Gillham sorted his book by disease, covering AIDS, diabetes, bipolar disease, cancer and others. He warns us to be patient because scientists must slog through government red tape, test, get approvals, raise money, test again, etc. etc. All that takes time. Even when new treatments become available, the author advises the public to see how it goes before jumping on the bandwagon. We've all seen some spectacular failures with new drugs, haven't we? As mother of a bipolar child, grandmother of a boy with sickle cell trait and widow of a man with lung cancer, I pray that God's hand be placed on these scientists to hurry the process and that these mortal servants of God and science work ethically, morally and without greed for the good of all mankind.
