It was a cool morning in the mountains of Republic, Washington, when Yarrow Watkins, a longtime Republic Seventh-day Adventist Church member, threw a coat over her pajamas and hurried out the door to start the sprinkler on her lawn. After flipping on the frost-free lever, she stepped back to avoid the water spray.

Suddenly she lost her balance and fell backward, landing on her left hip. “I have had falls before but that was the hardest landing I’ve ever had,” she says.
