What is Ali's physical defomity?
Ali had a "congenital paralysis of his lower facial muscles, a condition that rendered him unable to smile and left him perpetually grim-faced."
He had also had polio as a child, and his right leg was twisted and atrophied and is described as "sallow skin over bone with little in between except a paper-thin layer of muscle." Because of this, he walks in a tilted way by "[swinging] his scraggly leg in a sweeping arc."
Ali was often made fun of and called Babalu or Boogeyman by the neighborhood children because of these deformities.
