Our world offers reasons to despair all day long.

Wars. Terrorists. Mass shootings. Poverty. Homelessness. Natural disasters.

Ruthless, selfish, corrupt, insane, malignantly narcissistic politicians.

But the one that always brings tears for me is little kids dying of cancer.

That’s why I want you to watch to the end, ok?

Some of these stories have happy endings, enough, I guess, to keep these doctors and nurses and researchers fighting the odds and working for cures.

They are the true heroes, every one.
