Cape Town — U.S First Lady Michelle Obama ended her week-long visit to South Africa by meeting the Nobel Peace Prize winner Archbishop Emeritus Desmond Tutu - and getting a bit of a workout.

They visited the famous Cape Town Stadium in which some of the 2010 World Cup games were played, where the First Lady encouraged young people to protect themselves against HIV/Aids and use sport to stay healthy.

"You are VS - very special people," said Tutu in his cheery voice soon after he stepped into the room filled with young people and the media. He encouraged the youth to reach for the stars so that they can be anything they want to be in life.

The First Lady began her speech by joking with the Archbishop: "You are also a special person". Obama backed Tutu's words by telling them that one has to be a "VHP" - very healthy person - to inspire very special people.

Then she participated in the sporting activities. She dribbled the ball and did push-ups on the floor beside with the Arch while the children cheerfully shouted out president Obama's famous election slogan, "Yes we can!"

Former Bafana Bafana soccer star Mathew Booth was also present at the function. He said he was invited by the group Grassroots Soccer to take part in the project that educates, inspires and mobilizes the youth through soccer. "Meeting both Desmond Tutu and Michelle Obama is beyond what words can explain," he said.
