What does it mean to be a perpetual motion machine? Is intentional exercising the only way to better our minds and bodies, or can we find those same health benefits by other kinds of movement in our daily lives? This episode of Crucible answers the question: How can we be a perpetual motion machine without exercising? From simply choosing the stairs over the elevator to using a push mower instead of a riding mower, Marylee Atenhan talks with her guest and older brother, Bill Perry, about how to keep moving so you keep living healthy.
