Monday night, Charlotte Eisgrou and Ann Primack will ring in both the New Year--for the 103rd time.

Eisgrou and Primack are the oldest living identical twins, even though they turned 103 last Monday, they're both still kicking.

According to the Daytona Beach News-Journal, the two women were born prematurely on Christmas Eve in 1909, weighing a combined 7 pounds. A doctor rested them on the open door of a stove turned to a low temperature--incubators hadn't yet been invented--and they've remained best friends ever since.

The sisters weren't able to spend their birthday together, as both are recuperating from falls, but are otherwise healthy and remarkably spry: neither wears glasses or hearing aids.

"It's the genes," Primack said in 2009. "Genes are the whole thing."

"And it's milk," Eisgrou said. "It's milk and the genes."

Primack lives in South Florida, and Eisgrou lives in Daytona Beach. Both had long marriages and one son.

The oldest fraternal twins, Edith Ritchie and Evelyn Middleton of Scotland of Scotland, are 39 days older.

Happy birthday, Charlotte and Ann, and happy New Year!
