Cheers to Arthur Walters Jr., who recently laughed his way through his 104th birthday.The Washington D.C. resident brags that he’s lived more than a century and that he’s done so without having to regularly take any medications.When WJLA asked what his secret is to a long and happy life, Walters — a man with an infectious sense of humor — joked that “two good friends” have made aging a little more enjoyable. Though, they might not be the confidants you might be imagining. "People always say, 'what do you attribute to it?' and I always say, 'I have two good friends: Jim Beam and Jack Daniels,'” Walters said, adding "Those are my two good friends.”Asked whether drinking the two bourbons helped him live a long life, Walters simply replied: “Well, they've helped me along."In his 104 years, Walters has seen a lot. At age 22, equipped with his pilot’s license, Walters enlisted in the U.S. Air Force and served in the 96th Bomb Group in World War II. Today, he’s the only living crew member from his squadron, according to CNN.Striking a serious note, Walters offered some advice to younger generations.If there is something you want, you have to be willing to work for it, he said, adding that if you fail a few times, just “get back up and get back to it.”
