my blind friend once were in our late teens and he asked me to punch him in the face so we are joshing and do a fast light jab to him clocks him on the cheek not too hard, so then he says again and I kinda just want him to stop asking so i go a little harder at him. suddenly he did these rapid dolphin like clicks and dodged matrix style my jab i was impressed from that day never took him lightly and after that never felt i should really have to help him see or anything. after this article i am guessing he really honed his echolocation skills over the years
