ELI5: Why do our eyes water when we choke on something?
gpt
When you are choking, it is very dangerous as it can kill you. The human body does many actions to stop you from choking. One of these actions is coughing, pushing air up your throat. This also pushes air up your tear ducts. Where you tears normally "drain" out of. This pushes your tears back up to your eyes, and out. Making them water.
