World's Oldest Siblings, Dorothy Richards And Marjorie Ruddle, Are A Combined 213 Years Old (VIDEO)

Age is nothing but a number, but it's a really big number Dorothy Richards And Marjorie Ruddle: Together, these sisters are a combined 213 years three months, and 27 days.

Richards, who is 108, and Ruddle, a tender 105, have just been recognized by Guinness World Records as the world's oldest siblings.

They celebrated their achievement on June 8 with a tea party in the nursing home where Ruddle now lives. Richards hangs her cane at a nearby at a retirement home, according to ABC News.

For Ruddle's daughter, Pat Comber, the honor of setting a world record was secondary for the real reason for the day.

"Really, all we wanted was to get the two of them together," Comber told Guinness. "They haven't seen each other for three years because my mother has a slight disability and my aunt is quite frail."

Ruddle was happy for the reunion.

"I haven't seen [Dorothy] for ages, so it's very nice to be able to see her again," she told the BBC, but added that she felt "a little embarrassed" by all the attention.

Still, she was quick to offer up the secret to the longevity of her and her sister: "Hard work!"

The sisters should enjoy the honor, but there could be some competition on the way in the form of twins Edith Ritchie and Evelyn Middleton, who both turned 102 on November 15, and currently hold the Guinness record for "world's oldest twins."
