After suffering a stroke that left him partially paralyzed, Brian Wiley considers himself a lucky man.“Not many people get a second chance in life,” he said. “There’s got to be a purpose for it.”It’s been two years since the Forsyth County father, then 49, was rushed to the hospital. Wiley said he was at his mother’s home in Alpharetta when he felt something pop in the side of his face.“I could feel it go up to my brain,” he said.
