大衛•斯諾登（David Snowdon），美國明尼蘇達大學流行病學博士，1986年在明尼蘇達大學展開修女研究。1990年他將修女研究搬到肯塔基大學醫學中心的“山德士-布朗老化研究中心”，並在此擔任神經學教授。身為全球頂尖的阿爾茨海默病專傢之一，他曾在北美與歐洲各個科學會議中多次發錶研究成果，並於重量級醫學期刊，如《美國醫學協會期刊》、《老年醫學期刊》等發錶論文。

In 1986 Dr. David Snowdon, one of the world’s leading experts on Alzheimer’s disease, embarked on a revolutionary scientific study that would forever change the way we view aging—and ultimately living. Dubbed the “Nun Study” because it involves a unique population of 678 Catholic sisters, this remarkable long-term research project has made headlines worldwide with its provocative discoveries.

Yet Aging with Grace is more than a groundbreaking health and science book. It is the inspiring human story of these remarkable women—ranging in age from 74 to 106—whose dedication to serving others may help all of us live longer and healthier lives.

Totally accessible, with fascinating portraits of the nuns and the scientists who study them, Aging with Grace also offers a wealth of practical findings:

• Why building linguistic ability in childhood may protect against Alzheimer’s

• Which ordinary foods promote longevity and healthy brain function

• Why preventing strokes and depression is key to avoiding Alzheimer’s

• What role heredity plays, and why it’s never too late to start an exercise program

• How attitude, faith, and community can add years to our lives

A prescription for hope, Aging with Grace shows that old age doesn’t have to mean an inevitable slide into illness and disability; rather it can be a time of promise and productivity, intellectual and spiritual vigor—a time of true grace.
