Eye hath not seen, tongue hath not told,
And ear hath not heard it sung,
How buoyant and bold, though it seem to grow old,
Is the heart, forever young; — Forever young, — though life's old age
Hath every nerve unstrung:
The heart, the heart, is a heritage
That keeps the old man young!
The Song of Seventy. - A Thousand Lines (1846)
