Woman of the vine to Gilgamesh:

As for you, Gilgamesh, let your belly be full,

make merry day and night. 

Of each day make a feast of rejoicing,

Day and night dance and play!

Let your garments be sparkling fresh,

your hair be washed, bathe in water.

Pay heed to the child holding your hand,

Let your spouse delight in your embrace.

(...for death is the fate of man.)

This the advice from the Epic of Gilgamesh, as the king searched for immortality and mourned the loss of his beloved brother and companion. Written on clay tablets 2000 years BC in Mesopotamia.  Have we learned it yet?
