Most celebrities and professional athletes wouldn't think of stepping away from their comfortable lifestyle to put their lives on the line for others.

Except, of course, if you are the Klitschko brothers. The former heavyweight boxing champions have made it clear that they are jumping into the trenches in defense of their country.

Vitali Klitschko has been the mayor of Kyiv since 2014. He has made it clear that he is ready to fight:

“I don’t have another choice, I have to do that. I’ll be fighting,... I believe in Ukraine, I believe in my country and I believe in my people,”

Vitali's brother Wladimir enlisted in the Military reserves earlier in February. He said his love for his country compelled him to serve.

“The Ukrainian people are strong. And it will remain true to itself in this terrible ordeal. A people longing for sovereignty and peace.”

This is an excellent example to people around the world. These brothers have the means to flee Ukraine and be anywhere in the world, yet they choose to stand and fight. They choose to stand against tyranny and protect those who can't protect themselves.
