I'm no doctor, but I feel having functioning heart is quite important.

In fact, It is estimated that as many as 15 million children die or remain severely ill every year through potentially treatable or preventable cardiac diseases. 

The Chain of Hope charity, founded by Egyptian legend Sir Professor Magdi Yacoub, work around the world to provide to provide pediatric cardiothoracic surgery to children desperately in need. In an effort to support this extraordinary charity, do some good in the world, and burn off some christmas-calories, Hamzah Selim has been nominated to conquer the London Marathon on behalf of the Chain of Hope. 

Support his effort on the 23rd of April as he tests his heart, so that we can  together mend some little hearts.
