A little OT because it's not about a celebrity, but re the meaning of heroism:
One night a few years ago I went to meeting of the elected body of my small town, and (although it was not the reason I originally went) saw the fire department give a "certificate of commendation" to someone I knew slightly from high school, who is now an employee of a league of recreational sports teams. During the senior game, one of the elderly gentlemen on the team had a massive heart attack; my former classmate saved his life with CPR. The 9-1-1 call said "unconscious person," but the patient was conscious when the EMTs got there.
The organization had had the employees trained in CPR, but they were not medical professionals. Not sure if it should be called just part of the job, though.
Now that I think about it, I don't think the fire department actually used the word "hero," when presenting the certificate, but they said several times the gentleman would not have survived if the employee hadn't performed CPR, and that the family "thanks deity every day" that he did. The person being commended was gracious enough to thank his employers for having the staff trained in CPR, and thank the fire department for their good work.
The council people and everyone applauded in unison. One of the more uplifting moments I've experienced at a political meeting, for sure.
So it's possible to save a life without being at personal risk. I don't know if it requires "courage," but certainly presence of mind.
