All diseases run into one, old age.
Ralph Waldo Emerson
Forty is the old age of youth; fifty the youth of old age.
Growing old is no more than a bad habit which a busy person has no time to form.
I find that a man is as old as his work. If his work keeps him from moving forward, he will look forward with the work.
William Ernest Hocking
I get all fired up about aging in America.
