"Aren't they looking for trouble, stating that they're looking for someone "young" to fill the position?"
I've seen a lot worse on Craigslist. Recently I saw a "Personal Assistant" ad where an executive needed someone to travel with him and it said "Female preferred".
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
