NPR posted a piece about food that minimizes the risk of choking. In Japan, more people die from choking than from traffic accidents, and the difficulty that elderly person have swallowing is a leading cause of choking. The cooked food is pureed and then re-formed (with a thickener) into a dish that looks like regular food but is easier to swallow (no chewing required).
Meanwhile, The Washington Post had an article about the importance of knowing the Heimlich maneuver and CPR, both of which can help someone who is choking.
These highlight both sides of managing risk: (1) preventing a potential problem (choking) by eating foods that are less likely to cause choking, and (2) following a contingency plan (the Heimlich maneuver) if someone does start choking.
Bill Murray, who played a weatherman who saves someone from choking in the 1993 movie Groundhog Day, saved a man from choking in a Phoenix restaurant in 2016 by using the Heimlich maneuver, which he learned while making the movie.
