A reminder of the power of community.

"Moose" and "Porky" stepped into the gym, where I was treating Tom, a 78-year-old gentleman who was in danger of losing his right leg due to a nonhealing ulcer.

They had come to encourage their friend—to tell him that losing a limb was not the worst thing that could happen.

"Look at us," Moose said. "I lost my leg above the knee, and Porky lost his leg below the knee. We've both got prostheses. We're walking around without assistive devices and doing just fine. Heck, we walked all around Summerfest yesterday and did great."
