What happens when one of the greatest pioneers of mixed martial arts sits down with one of the world's most respected Brazilian Jiu-Jitsu masters?

You get an unforgettable conversation that goes far beyond fighting.

In Episode 25 of Coffee Time with Carlos Machado, Carlos welcomes MMA legend, Pancrase champion, UFC veteran, author, medical scientist, and martial artist Guy Mezger for an honest discussion about the evolution of combat sports, the realities of competition, health, aging, and what it truly means to dedicate your life to martial arts.

Guy shares incredible stories from the early days of no-holds-barred competition, explains why modern MMA has become a true sport, and reflects on how wrestling forever changed Brazilian Jiu-Jitsu and mixed martial arts. Together, Carlos and Guy discuss training smarter as we age, maintaining strength and mobility, avoiding unnecessary injuries, and why longevity should become every martial artist's ultimate goal.

The conversation also takes a deeply personal turn as Guy opens up about the stroke that unexpectedly ended his fighting career—a life-changing experience caused by the prescription drug Vioxx—and how that event ultimately redirected him toward medicine, health, nutrition, and helping others live longer, healthier lives.

Whether you're a lifelong martial artist, an MMA fan, a BJJ practitioner, or simply someone interested in health, resilience, and personal growth, this episode is packed with wisdom that extends far beyond the mats.
