What's the secret to a long life?

For 101-year-old Andrew Slavonic, it's a daily Coors Light.

Slavonic, who celebrated his 101st birthday on Dec. 1 with his family and friends in McMurray, Penn., has been drinking one Coors Light every day at 4 p.m. for the past 15 years.

Slavonic, a World War II Air Force veteran, and his son, Bob Slavonic, joined the "Fox & Friends" co-hosts Sunday to discuss their daily ritual.

"I tried several other beers, but they just didn't feel like the right one," Slavonic said. "So I came across Coors Light with its flavor ... and I really enjoyed it. And I've been drinking it for the last 15, 20 years."

He said he doesn't have a strict one-beer-a-day rule, and sometimes it's two or three.

“We got to have the one at 4 o’clock though. That’s the most important one,” Slavonic said.

Once MillerCoors heard about the centenarian's enthusiasm for the brew, the company delivered a belated birthday present: a Coors Light branded fridge, completely stocked with Coors Light.

As part of their gift, MillerCoors also gave Slavonic hats, pullovers and sweatshirts for himself and his family, and they invited him to take a tour of their brewery in Golden, Colorado.

"Fresh beer's always good!" the younger Slavonic said.
