An Oklahoma couple married for over 63 years shared a bond so strong they died on the same day, unbeknownst to each other.Back in 1951, Bob and Barbara Pettis were married, vowing “til death do us part.” On June 30, they both departed together. According to The Oklahoman, 82-year-old Barbara died in a nursing home after battling a number of health problems, and 85-year-old Bob died of pneumonia in a hospital just a few hours later.
