[05:30.19]In 1969Ben graduated third in his class from Southwestern High
[05:37.32]and received a full scholarship to Yale.
[05:41.26]After Yale he obtained grants to study at the University of Michigan Medical School
[05:48.11]This was the start of a career that was to lead him,at age33,
[05:53.67]to be appointed senior brain surgeon at Johns Hopkins hospital.
[05:59.71]From around the world.
[06:02.34]other surgeons came to seek his counsel.
[06:06.92]In April 1987a German doctor
[06:11.04]arrived with the records of Siamese twins,newborns Patrick and Benjamin Binder
[06:17.99]The boys had separate brains,
[06:21.47]but at the back of the heads,when they were joined,they shared blood vessels.
[06:27.53]Their mother refused to sacrifice either child to save the other.
[06:33.38]Surgeons knew of no other way to proceed.
[06:38.03]In many cases,when Siamese twins separated at the back of the head,
[06:43.91]one child survives and the other either dies or suffers severe mental injury.
[06:51.66]Carson came up with a plan to give both twins the best chance of survival:
[06:58.12]stop their hearts,
[07:00.68]drain their blood supply completely
[07:04.02]and restore circulation only after the two were safely separated.
[07:10.26]The entire operation took 22hours and required a 70-person team.
[07:17.08]After the twins'hearts were stopped and their blood drained,
[07:22.12]Carson had only one hour to separate the damaged dlood vessels.
[07:28.39]He worked smoothly and quickly,
[07:31.55]easing his instruments deep into the brains of the two infants.
[07:37.61]Twenty minutes after stopping the twins'circulation,he made the final cut.
[07:43.78]Now,working with his team,
[07:46.73]he had 40minutes to reconstruct the blood vessels that had been cut open
[07:53.39]and close Patrick's head.
[07:56.26]Another team would do the same for Benjamin.
[07:59.92]Just within the hour limit,
[08:02.98]the babies were fully separated,and the operating tables were wheeled apart.
[08:09.22]The students of Detroit's southwestern High sat silently
[08:14.26]as Ben Carson described his life's journey
[08:19.54]from an angry street fighter to an inernationally distinguished brain surgeon
[08:26.02]"It's important that you know there are many ways to go,"Dr.Carson told them
[08:33.36]"Becoming a brain sugeon is perfectly possible.
[08:37.80]But you don't have to be a surgeon.
[08:41.67]There are opportunities everywhere.
[08:45.01]You just have to be willing to take advantage of them.Think big
[08:51.57]Nobody was born to be a failure.
[08:55.04]If you feel you're going to succeed and work your tail off-you will succeed!"
[09:03.09]Pausing,Ben Carson turned to his mother who was sitting in the front row.
[09:09.85]"I'd like to thank my mother,"Carson said in closing,
[09:14.32]"for all the success I've had."
[09:17.37]Southwestern High's entire graduating class stood and clapped for a solid five minutes.
[09:25.73]Tears welled in Ben Carson's eyes.
[09:30.59]Afterward,Sonya Carson embraced her son fondly."It's really true,Bennie,
[09:38.85]"she said. "You can be anything you want to be.And you've done it!"
