Expect from life

we are bound to expect
certain things. We are almost sure
to get them:
a certain amount of misery
a certain amount of discomfort
of diarrhea
of fever
a certain amount of piercing earache
of teeth-grinding headache
of stabbing toothache
of uncontrollable nausea
of blinding migraine
of involuntary groans, especially
a certain amount of hearing
improbable numbers of people say:
"I've never been sick a day
in my life."
