That "Iowa Nice" is a constant in Jason Momoa's life. He's always doing great stuff for the planet and for the people inhabiting the planet. His friend Travis Snyder has been battling Leukemia on and off for many years. Travis is the guy who started the Color Runs around the country. When Travis beats his fight, it's because of a bone marrow transplant, but when the cancer comes back, he needs another transplant. Jason learned of the need for people to get on the bone marrow registry through Travis. He's now publicly asked his millions of followers to get on the registry... not just for Travis, but for children battling leukemia, as well.
