If you're looking at old photos that pre-date 1920, you're entitled to point out all the people in the pictures to anyone who'll listen and tell him or her that those people are all probably dead now, unfortunately. Except you have to point out each person individually, one at a time. "See him? He's probably long gone." "That one there, with the parasol? I imagine she's dead."
Q. Why does a haemotologist call blood poisoning "septicemia"?
A. Because when he gets the blood test results back and he sees that you have it, he will say: "Now, I don't want you to panic. You'll have to get treated immediately. So you don't have to do anything at all, ex septicemias soon as possible!"
