Forget retirement if you want to remember longer.

A new study shows delaying retirement reduces the risk of Alzheimer's.

Barbara Delabano, 83, still works full-time as an administrative assistant, and she loves it.

"I like the routine of coming to work every day," she said, "and being with a group of people every day."

French researchers say working keeps people sharp.

They followed 500,000 elderly people. Those who stayed on the job lowered the risk of Alzheimer's or Dementia three percent for each year they delayed retirement.

UT Southwestern Dr. Mary Quiceno said the study makes sense.

"It's kind of the interaction -- being at work, building your cognitive reserve, but also, interacting with people," Quiceno said. "Probably getting physical exercise, being physically active, depending on your job. I think it's probably an interplay of all those things that helps people reduce the risk of Dementia."

"As long as I enjoy it, I don't see any reason to retire," Delabano said. "Occasionally, I'll say an extra day off during the week might be nice."

And research shows that attitude will help keep Delabano's mind as young as she is at heart.
