Megadeth frontman Dave Mustaine might be 59 years old, but he could still probably kick your a**.
The heavy metal legend just earned a purple belt in jiu-jitsu from the Gracie Barra Spring Hill Brazillain Jiu-Jitsu & Self Defense school near Mustaine's Tennessee home.
Mustaine has been studying martial arts since 1999, also training in taekwondo, Ukidokan karate, and other disciplines.
Flat out AWESOME!
