Swedish twin sisters Gunhild Gallstedt and Siri Ingvarsson celebrate their 100th birthday this weekend surrounded by three generations of family, Sweden’s Dagens Nyheter reported on Friday.
The sisters were born in Malmo on January 30 1905 and have lived in the same apartment block in Stockholm for the past 60 years.
Celebrations this weekend will involve children, grandchildren and great-grandchildren.
The sisters, both widowed, are described as ”unbelievably agile”, and manage day-to-day living without any practical help.
”I am the eldest by half an hour but Gunhild is the boss,” said Siri.
The secret to longevity, according to Gunhild, is a good book and a late night.
”I like reading thrillers and sometimes don’t turn out the light until five in the morning,” she said. — Sapa-DPA
