The average human body can survive for up to three weeks without food - Gandhi famously managed 21 days of complete starvation. Water, however, is a different story. At the very most, we can live without water for a week. Water is required by every cell in our body. It lubricates joints, regulates temperature, and flushes waste. For the homeless, living on the streets without access to water, death is a near and imminent certainty unless water can be found.
Showing a tenderness and awareness beyond his years, this boy is fighting against that fact. With a backpack full of water and some containers, he's moving down a line of homeless people, topping up their water supply and making sure they all stay hydrated, making the world a tiny bit better for each of these people. It's one small act of kindness that makes the world a little brighter for those who need a ray of sunshine most of all.
