The story below is LONG, and is 6 years old but I just listened to a podcast about him yesterday, he's doing amazing things working with children and drug addicts and even the slave pygmies of the Congo, all while still a pro fighter. Amazing. "Wren got the opportunity to join a humanitarian mission to Haiti, where he watched children climb through trash piled like snow drifts to reach drinkable water in the wake of the catastrophic earthquake that leveled the country’s capital city. In the next year, Wren went on missions in Rwanda, Uganda, Tanzania, Kenya, and the Democratic Republic of Congo."

Here is the YouTube video, which talks about bullying and what he went through and what he's doing now and then his amazing humanitarian service where he is doing these Humanitarian missions. It is something I'm actually going to show my kids:
