- A Contribution to Statistics by Wislawa Szymborska
Out of a hundred people
those who always know better
-- fifty-two
doubting every step
-- nearly all the rest,
glad to lend a hand
if it doesn't take too long
-- as high as forty-nine,
always good
because they can't be otherwise
-- four, well maybe five,
able to admire without envy
-- eighteen,
suffering illusions
induced by fleeting youth
-- sixty, give or take a few,
not to be taken lightly
-- forty and four,
living in constant fear
of someone or something
-- seventy-seven,
capable of happiness
-- twenty-something tops,
harmless singly, savage in crowds
-- half at least,
cruel
when forced by circumstances
-- better...
