Take a look at this kid.
Lin Hao is marching with Yao Ming. Thats a very small 9 year old marching with a 7 foot tall basketball player.
The child is an earthquake survivor. 20 of the 30 children in his class died. He survived. He freed himself from the rubble, and WENT BACK, risking injury, to save other surviving classmates.
NBC reported that when he was asked why he did this, he answered that he was the hall monitor, so it was his job to look out for everyone's safety.
Heros sure come in all sizes.
