or walk.

destroyed brain signals to the right side of my body.

     But no son of my dad' s was going to be disabled.Every morning before breakfast and every evening

before bed, my dad placed me on the bedroom floor to exercise my right leg.The muscles were shrunk

and twisted together.Back and forth up and down, my dad pushed and pulled the muscles into shape.
