Mary Todd Lincoln's demons blamed on vitamin B-12 deficiency.

Carolyn, Dr. Sotos is the same doctor who wrote a book called "The Physical Lincoln." In the book Dr. Sotos argues that Abraham Lincoln suffered from a rare genetic cancer syndrome called MEN2B (multiple endocrine neoplasia, type 2B). Dr. Sotos feels Lincoln had less than a year to live when he was assassinated. I wonder if he is now in the early stages of writing one on Mary Lincoln's health.
