KNOXVILLE, Tenn. (WVLT) -- Every morning, 95-year-old David Barber wakes up and starts his day like he did when he was in his 20s.
"I don't like sitting around and doing nothing. I like to keep going like I have ever since I coached football and basketball and worked for the sheriff's department," the Tennessee man said.
Barber served his country, which is how he met the love of his life, Phyllis.
"I was in the Marine Air Force, ordnance specialist," he said. "I armed aircraft, bombs, machine guns and so forth.
"I met her on a double date, but she wasn't my date," Barber said. "She was in the Marines. She was stationed at Santa Barbara. The day that I made Corporal, I made Sergeant, so I outranked her all our life."
On their first date, Phyllis poured ice water on her future husband.
"It was the best date I ever went on," he said. "When she pulled that trick on me, I knew I was going to get even with her, and I did for 65 years. Back when we got married, you got married for life. Of course, we never had any ideas of separating anyway."
Phyllis died 10 years ago, just months after she was diagnosed with Alzheimer's Disease. Inspired by her life, Barber said he felt a call to action ever since — a call he continues to answer, even at age 95.
"When she passed away, I sold my house and I just didn't have anything to do, and so I decided I'd volunteer and do something to help other people," he said. "I like helping other people."
Most days, Barber can be found volunteering at LeConte Medical Center in Sevierville, Tennessee, helping push wheelchairs and directing those who need some help finding their way around. Barber said most of the patients he helps are younger than he is.
"He's an inspiration to all of us," said Doug Michael, a volunteer at LeConte Medical Center.
From protecting our country during times of war, to helping the people of Sevier County in their time of need, Barber said a higher calling keeps him moving, as long as he's able to answer it.
"I pray every day that God will bless America," he said. "We depend on Him."
