My name is Tim Kennedy and I have a problem: I only feel alive when I’m about to die.

I’ve killed evil men on multiple continents, fought in main event bouts in the UFC, served as a Green Beret, an EMT, a firefighter, and a cop. I’ve hunted Nazis, drug runners, Abu Musab al-Zarqawi, human traffickers, rhino poachers, Al Qaeda, the Taliban, wildebeests, elk, bears, and have the recipe for the perfect soufflé. I fly helicopters, jump out of airplanes, dive mixed gas to the ocean depths, wrestle bulls with my bare hands, lift heavy weights, blow things up, and am proficient in just about every weapon under the sun. I train warriors, own companies, serve my country—and I’m just getting warmed up.
