Hundreds of children born and bred on the streets seek thrills in death-defying ways.
Zaid, one such boy, who survived a near fatal collision while performing a stunt on a running Mumbai, India, local train, has now turned a campaigner against the dangerous act.
After battling for his life in a Mumbai hospital, a changed Zaid said, "I will tell people that they should get inside and not be outside. If there is no space, they should take the next train."
