Remember the Ice Bucket Challenge craze this summer? Meet the mom who started it all. When Nancy Frates's son Pete hurt his wrist in a baseball game, he got an unexpected diagnosis: it wasn’t a broken bone, it was ALS, and there is no cure. In this inspiring talk, Nancy tells the story of what happened next.

This talk was presented to a local audience at TEDxBoston, an independent event. TED editors featured it among our selections on the home page.
