✹ About Sunday 11 September 1664 Louise Hudson on 13 Sep 2017 • Link "Fell down dead." Probably used to mean "as if he were dead" or "it looked as if he fell down dead." Maybe the witnesses thought he was dead until he started to revive. They didn't know about heart stimulation or mouth-to-mouth resuscitation then. A lot of people probably did die in Pepys' time who would be saved today.
