=Old young, and old long.=[768]
You must leave off the irregularities of youth be-times if you wish to
enjoy a long and hale old age; for
=Young men's knocks old men feel.=
"The sins of our youth we atone for in our old age" (Latin).[769]
=Rub your sore eye with your elbow.=
He who laid down this rule of sound surgery was a man _qui ne se
mouchait pas du talon_; he did not blow his nose with his heel. If a
speck of dust enters your eye, close the lid gently, keep your fingers
away from it, and leave the foreign body to be washed by the tears
to the inner corner of the eye, whence it may be removed without
difficulty.
