Their grandson Randy Yeager said he has been inspired in his own 13-year marriage by his grandparents' loving and lasting marriage.
"Grandpa and I were talking this summer about all of the people getting divorced for this reason or that and he mentioned that nobody stays together anymore," Randy Yeager wrote to ABCNews.com in an email. "I told [him] that my wife Mara and I would never be getting a divorce and he said, 'That's because you're old school, like me!'
"That was one of the greatest compliments I could have ever received and one I will strive to live up to for the rest of my life," Randy Yeager said.
The couple were put in a casket together holding hands for their funeral this week, but are being cremated and will have their ashes mixed before burial.
"All their life has been together," Sheets said. "So, when it came to the funeral home, the family asked, 'Can we have them put in the casket together holding hands?' Because that's the way their life was."
