Americans can’t get enough of an adrenaline rush. Just ask former AIG vice president of claims Kevin Donaldson, who found his passion in the game of paintball.

On the Fox Nation special "Paintball:  America’s Secret Pastime," Donaldson explained that his life in corporate America just couldn’t compare to his involvement with paintball, so he decided to quit.

"Ultimately, one day, I said 'I’m done. I’m done with corporate life,'" he said. "Just couldn’t get enough paintball. It was my whole life."

Donaldson said he initially quit his "very lucrative" job to open a paintball store. Eventually, he began competing in and running competitive tournaments. He is now manager and captain of the professional paintball team Master Blasters.

Many members of the team are "average Joes" who work as auto mechanics, nurses and teachers during the week, but seek the rush of the game on the weekends. Donaldson explained that his teammates have not only become his best friends but also his family.

"I try to instill a family environment. It’s one of those jobs that you have to do as captain of the team. You have to do what’s best for the whole, not the individual," he said.

"This family has been through a lot together," he went on. "We’ve been practicing on this field in Newburgh [N.Y.] for years. Right now our weekend training sessions are building up to some pretty big tournaments."

The Master Blasters were founded in 1986 and play in tournaments all over the world, according to their Facebook page. The Fox Nation show brings you inside the Blasters' training for their most competitive tournament: the Chicago Windy City Classic.
