“Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young
“While one finds company in himself and his pursuits, he cannot feel old, no matter what his years may be
“To keep the heart unwrinkled, to be hopeful, kindly, cheerful, reverent that is to triumph over old age
“Age is not a particularly interesting subject. Anyone can get old. All you have to do is live long enough
