well, sometimes you are lucky to get a break.....it can be very overwhelming.....I think a joke i once heard is appropriate for this question....
A WOMAN WAS FOUND DEAD ON THE SHORE LINE OF A BEACH, THE CORONER CAME TO EVELUATE THE CASE, AND ALTHOUGH THE WOMAN WAS DECAPITATED, THE CORONER SAYS TO HIS ASSISTANT "WELL AT LEAST I KNOW IT WAS A NURSE.."
THE ASSISTANT SAYS BACK TO THE CORONER "HOW DO YOU KNOW THIS, SHE HAS NO ID, NO UNIFORM ON THAT WOULD LEAD ME TO BELIEVE SHE WAS A NURSE"
TO THIS THE CORONER REPLIES "3 THINGS TELL ME SHE'S A NURSE....HER STOMACH IS EMPTY, HER BLADDER IS FULL, AND HER ASS IS CHEWED OUT"
seriously though, on 12 hr shifts where i work you get 3 15 min breaks, and 1 30min lunch....good luck to you!
