Her long life can be attributed to her genetics (both parents lived into their 80s), her active lifestyle and an optimistic attitude. She enjoyed many hobbies and physical activities, and believed that laughter contributed to her longevity. She poured olive oil on all of her food and skin, which she believed also contributed to her long life and youthful appearance.
