Four years ago, Marco Ferreira was riding his motorcycle down an isolated road in Los Angeles when he hit some grout and had an accident.
Though he was wearing a full helmet, leather pants and jacket, Ferreira suffered a traumatic brain injury.
When he woke from a six-week coma, his wife, Wendy Tucker, was there.
"You didn't walk, you didn't talk, and you couldn't feed yourself for seven months," she says during a visit with the 48-year-old Ferreira to StoryCorps in San Francisco. "Since then, it's just been getting better all the time."
