Guns N’ Roses icon Duff McKagan made a new interview Rolling Stone Music Now podcast and revealed what makes him going on after the age of 55.

Duff said that his daughters, martial arts and having lots of sex make him look so young. Duff also said that when he sees Mick Jagger on stage, he feels like a kid again.

Here is comments, transcribed by Alternative Nation:

“I feel like I have aged fifty years since [2006]. Well thank you, martial arts, lots of sex I guess. To be quite honest with ya. I have daughters that keep me young, you know? I think having kids, growing up in their teenage years, eighteen and twenty one it keeps you going.

Playing rock and roll, the secret now is that we aren’t our dads, we aren’t our dad’s fifty-five for sure. We got better water and all of that and whatever but there is also The [Rolling] Stones. It comes down to the Stones. They keep you young, they are out there doing it. Mick [Jagger] is gonna be better and all of that but I still feel like a kid when I still see the Stones out there touring, like I better get started.”
