Use of the term hero for sports figures goes back as least 80 years to the song "You Gotta Be a Football Hero," written in 1933.
To the guy who begrudges his "friend's" inflated union salary as a firefighter, maybe he should start working swing shifts, enter burning buildings (even with maximum training) for a few months, pull out the charred remains of a kid, show up at a home where a guy ate his shotgun, struggle to get a 600 pound heart patient out of a house and down a set of winding stairs, hold back a mother whose child can't be rescued.. climb a ladder wearing a hundred pounds of gear in hundred degree heat and -20 degree snow, , Maybe he should respond to a car crash (as happened in New Hampshire this week) to find his daughter was a fatality as a result of an apparently distracted driver. and see if he thinks his "friend's" the salary is so inflated. Does the firefighter deserve a discount? I don't know, but I get discounts just because I've lived more than 55 years.
