Washington — Doctors told Tim Thomas that two-thirds of his brain were getting less than 5 percent blood flow and the other third was averaging about 50 percent. His wife, Melissa, and oldest daughter, Kiley, started crying. Thomas didn’t react — because he couldn’t process what he was hearing. “I couldn’t believe it because I couldn’t function well enough to understand it,” said Thomas, a native of Davison, near Flint.
