TINTON FALLS, N.J. (CBSNewYork) — What are the secrets to an everlasting love?

With Valentine’s Day around the corner, CBS2’s Christine Sloan got answers at the Seabrook retirement community in Tinton Falls from older couples whose marriages have endured decades.

Louis and Lucille Kramer have been married for more than 70 years.

“I will say he was handsome,” recalls Lucille.

“A beautiful redhead,” Louis describes.

They are still madly in love.

Their secret? Having a sense of humor from the moment they met in high school and Louis went off to the service in World War II.

“He was witty,” Lucille says. “He would always come out with a joke.”

Louise and Pat Driscoll have been married for 51 years.

Louise, a ham on stage, still appears in musicals.

“You must have your own interests in life,” she says. “You can’t follow each other around every minute.”

But Pat says traveling is the key to an exciting relationship — and so is romance.

“We may hold each other’s hands, also,” he says with a laugh.

They also focus on the good.

“Look at the positive aspects of your partner,” Pat says. “Don’t dwell on the negative.”

For the Kramers, “we’ve been very active our whole life,” says Lucille. “We’re so busy.”

Talking to other couples, they say the ultimate secret to a long-lasting relationship is respect for each other.
