Keith Davison lives in Morris, Minnesota. He's a 94 year old retired judge, and for 66 years he was married to Eve, until she passed away in April, 2016. He's been lonely since then. "You get used to having a person there to enjoy," he says, "and now this doggone place is just so quiet." So he found a remedy.

He had a 32-foot long pool with a diving board built in his back yard, and invited everyone in the neighborhood to enjoy it. Now his yard is filled with the joy of kids splashing around. "I knew they'd come." he says. "I'm not sitting by myself looking at the walls. The pool has been a diversion from that."
