McDonald's employee Ruthie Shuster turns 100 on Wednesday (March 3). She has worked at the Big Mac Museum in Irwin for 26 years.
"I have no secrets, I just live one day at a time. Everyday is a bonus day for me," Ruthie said during the KDKA Radio Morning Show Wednesday.
Ruthie still works three days a week.
When the centenarian was asked why she still works she said, "Because I like it. It gives me something to do. And they are nice to work for. I like my job."
