To judge by this poem, the ingredients of a happy life - as spelt out by the Roman writer Martial and reinterpreted by the Irish poet and dramatist Brendan Kennelly in his book Martial Art - have not changed much in 2000 years.

A HAPPY LIFE

What constitutes a happy life?

Enough money to meet your needs

steady work

a comfortable fire

a clear distance from law

a minimum of city business

a peaceful mind and a healthy body

simple wisdom and friends

enjoyable dinners and plain living

nights free from care

a virtuous wife who's not a prude

enough sleep to make the darkness short

contentment with the life you have,

avoiding the sneer, the poisoned sigh;

no fear of death

and no desire to die.
