A New Jersey woman who was the oldest American person Adele Dunlap has died, at the age of 114. Now the oldest known person living in the U.S. is 113-year-old Delphine Gibson of Huntingdon County, Pennsylvania, NY Post reported.

As it was noted, Dunlap did not have an explanation for her longevity, and neither did her children. According to her son, she smoked, and when his father had his first heart attack, they both gave up. Adele ate anything she wanted and she was not a drinker but had occasionally enjoyed a martini, he added.
