The mouth of an old man may smell but the advice coming form it is sweet.

Giving advice to others is not really as helpful as if you yourself act upon that.

The mouth of a man is a terrible opening and his tongue is a terrible fire dragon.

To prescribe medicine for the dead and to give advice to the old is the same thing.

A man starts growing old when his wishes turn into regrets.

Ask for advice, and then use your brain.
