I told you about our friend photographer Joao Silva from the New York Times, an old friend from South Africa, who lost both his legs to a land mine in Afghanistan in October. Joao took his first steps at Walter Reed this week. Take a look. And if chemo is knocking you out right now and you don't know how you are going to get through these next months. Watch this video of Joao and please go put on your running shoes. You will feel so much better. I promise. Don't give up.
