In every animal that walks upright, the deficiency of the Fluids that fill the Muscles appears first in the highest Part: The Face first grows lank and wrinkled; then the neck; then the breast and arms; the lower parts continuing to the last as plump as ever; so that covering all above with a basket, and regarding only what is below the girdle, it is impossible of two women to know an old from a young one.
Benjamin Franklin
