Wilma Wellner still enjoying life at 100 years

Centenarians are happy and optimistic individuals enjoying life at or beyond the age of 100 years while having low rates of health problems.  The majority of centenarians do not feel their chronological age; on average, they report feeling 20 years younger. They also tend to have positive attitudes, optimism and a zest for life. Could it be that personality characteristics and worldviews play a more significant role than genetics, diet, or exercise? Centenarians are certainly a group of astounding individuals, each with their own particular rational for his or her longevity. 

Wilma Wellner certainly fits that pattern. She observed her centennial birthday yesterday, and continues to enjoy life at the age of 100 years.
