Dierks Bentley is still hitting the stage hard in his late 30s. And he reveals one of his secrets to success on the road.

Dierks tells CMT that he drinks a couple during each show.

He says it serves two purposes. One, it numbs the pain of being away from home.

And two, Dierks says it helps get him fired up and feeling like he's part of the party.

Dierks says, "It would be pretty hard to entertain 15,000 people without engaging in a little bit of what's going on out there."
