Welch's Biblical brain potion

Blame It on the Brain?
by Ed Welch

Finishing this up, and it was excellent, well-balanced and on target Biblically.
He divides it into some ailments which are traceable to the brain, or biology, other ailments which may be biological or moral/spiritual, and a final category of ailments which cannot be relegated to the brain but certainly have moral components. For a sense of Welch's perspective, he puts in the first category Alzheimers and dementia, in the second, depression and attention deficit disorder, and in the third, homosexuality and alcholism. The ADD and homosexuality chapters were outstanding.

My only lingering question is whether Welch is related to the Welch's grape juice people, which would be interesting, as he writes well on alcoholism and the strenghts and weaknesses of Alcoholics Anonymous.
