"How Safe Is the Artificial Turf Your Child Plays On?"

"Soccer coach Amy Griffin was in a Seattle hospital visiting a young goalie who was receiving chemotherapy when a nurse said something that made the hair on Griffin’s neck stand up.

It was 2009. Two young female goalies Griffin knew had been diagnosed with non-Hodgkin lymphoma. Griffin, associate head coach for the University of Washington’s women’s soccer team, had started to visit the women and other athletes in local hospitals, helping them pass the time during chemo with war stories from her three decades of coaching.

That day, the nurse looked down at the woman Griffin was sitting with and said, 'Don't tell me you guys are goalkeepers. You're the fourth goalkeeper I've hooked up this week.'"
