Actually I think they do it for everyone. They certainly did for my sister.
They also did it for my father who was 78 at the time. The paramedic told me they did everything they could but could not revive. They worked on him from his friend’s house where he fell asleep from the house to the ER room they worked on him even in the ER room but my father unfortunately did not come back. So yes they also do that for non-celebrity.
