“That is where the expression “saved by the bell” came fom.”
Pretty sure that is a boxing term champ.
The round ending bell sounds as the referee is still making the 10 count, so the boxer on the floor was saved by the bell from being counted out.
It was used many many years before boxing became famous.
“You may have heard the popular expression “saved by the bell” in reference to the popular ‘90s TV show or because it’s equated to a centuries-old practice in which people were buried with bells in their coffins so they could alert others in case they were inadvertently buried alive.Jan 5, 2023”
