“Consider sports. They’re only about creating constraints (sidelined fields, dimensioned courts, groomed fairways, etc.), putting a worthy adversary in front of us (a team, one person, ourselves), and pushing at our limits until we break through to that one place that lives just beyond both adversary and constraint: the basket, goal, hole, end zone, finish line. If you’ve ever felt high after kicking a ball into a goal while 11 people tried to stop you, or you just watched your favorite team do so, you know the ecstatic thrill of embodied freedom through sport.”
