I take it that you do not feel comfortable with the position, please dont hold back
But seriously, your reaction is not unusual in the slightest. Take for example hmmm the City of New York. How many million people/adults live there? How many apply to be a police officer (getting shot at), firemen/women (turned into a crispy critter), or any other form of public service job that requires one to risk life and limb as a normal part of the job description.
What %age of that total population is willing to take those risks as a job description? Not one whole hell of a lot.
SOME people will step up and volunteer to perform the service and actually look forward to the opportunity to serve, but most will not (primary reason,fear of getting involved). Still as long as 'Enough' get involved that would be all that matters in the end game.
Thanks for your reply
