It's the afternoon of February 12, 1962, in a hospital waiting room on the outskirts of London, England.

15-year-old schoolboy David Jones brushes his long hair from his face and watches the busy doctors and nurses at work.

To pass the time, he begins to drum rhythmically on his leg.

Sitting next to David is his school principal.

Annoyed by David's incessant drumming, he slaps his hand and David stops.

But the pain from the slap is nothing compared to the ache in David's head, the reason

he's at the hospital in the middle of a school day.

A few hours earlier, David was hit in the face by a classmate.

The two were fighting over a girl they both liked, and David got the worst of it.

He now sports a deepening bruise around his

eye and suffers from double vision that won't go away. Finally, a nurse calls David forward and leads him

to a separate room to see the doctor. Upon seeing David's long hair, the doctor gives a

disapproving shake of his head, then pulls out a small flashlight from

his pocket and shines it into David's eyes. David winces as the doctor passes the light back and

forth across his face. Then, turning off the flashlight, the doctor explains that the punch David

received has caused what could be permanent damage to David's left eye.

He then leaves David to inform the school principal.

Alone, David rises and peers at himself in the room's mirror.

He's amazed by what he sees.

In the bright light of the examination room, the pupil of his right eye is as small as a pinprick,

but the pupil of his left eye is dilated, almost as large as the entire iris.

A huge smile spreads across David's lips.
