As someone who was thinking of being a dentist. It's a job that needs done. They wear gloves and clean the mouth so it can't be that terrible. Oral care is incredibly important.
Are we talking about dentists or pornstars now?
What...the hell are you talking about?
1. A job is a job...and it's called ACTING.
2. They're not actually being tortured. IT'S CALLED ACTING
3. It's not real blood or body fluids. IT'S CALLED ACTING
4. What's wrong with nudity?
5. They're not actually being killed. You...you understand that right? It's just part of the movie. They're...they're actors...
What in the honest hell are you talking about here?
Is it? What sort of argument is this even?
This isn't a job but a piece of equipment for many jobs.
Not all jobs are safe. Lots of jobs are vital to the continued existence of our society. Not everyone can be a Doctor (though you seem to think that job is "gross") or a Lawyer or something like that. Some people who have no chance of getting those nice jobs take these jobs because the pay is better so they can live a happy, even if short, life.
