A local man survived the type of stroke that normally kills 80 percent of its victims. He’s doing so well, he just moved to Europe and is enjoying life to its fullest. It’s been three and a half years since Ken Harrawood suffered a stroke. It hit while he was driving to Y-12 for his first day of work with Bechtel. He now lives in Manchester, England.
Adam Hill gets the tools in place for the next life-saving surgery in the interventional radiology lab at Fort Sanders Regional Medical Center. As lead tech, Hill knows this place like the back of his hand. He never dreamed he’d be a patient receiving treatment here, suffering from a ruptured aneurysm, like so many patients he’s helped treat.
Since recovering from a stroke, Paul DeWitt appreciates simple pleasures that are easily taken for granted. He grasps a cup of coffee. He smiles and laughs. He even appreciates the ability to whistle.
