After reading the whole thread it's interesting to see how some professions really do look "ill" at certain interests.
I can give you some insight as to things in medicine. I'm a doctor.
Yep. And, I think our professions also influence much of the company we keep. From the OP, with my core group of seven, we've got a Financial Advisor (broker), an Office Manger, a Hair Salon owner, an owner of a painting company, two grocery route salesmen, and a freelance computer tech.
The one most liberal with allowing anyone to know that he games? One of the route salesmen.
The four that actively deny it and even lie to their wives about gaming? The broker, Officer Manger, other route salesman, and the painting company owner.
The two that don't advertise but will own it if outed? The Hair Salon owner and the freelance computer tech.
I don't know if age has anything to do with it. I know I was more likely to talk about it in my 20's than I am today. I recently asked the painting company owner why he lies to his wife about gaming. I mean, gaming is a very inexpensive hobby. You get tons of fun for your entertainment dollar. And, you're certainly not out doing anything that can get you into trouble as can sometimes happen at a bar or when playing pool or darts or the like.
It's good, wholesome, extremely fun, entertainment.
So the answer from my friend came, "I'm a 46 year old father of two. My wife is going to lose respect for me if she learns that I'm gaming. She just won't understand."
Well, there you have it.
