If the boy is old enough to get a tattoo he is old enough to go alone.
In this life the old believe everything, the middle-aged suspect everything, and the young know everything.
The older the fiddler, the sweeter the tune.
No stake ever grew old with the bark on.
Most people like the old days best – they were younger then.
A man is as old as he feels himself to be.
Wrinkled as a prune.
The old ox plows a straight furrow.
Old as dirt.
Forty is the old age of youth; 50 is the youth of old age.
