Gambling etc.

Ok, I've been meaning to ask this for a while, and just found some time in my extremely busy schedule (who am i kidding). A LOT of my students (guys) like to bet on football, baseball, play poker, and do other types of gambling online. I don't think any of them have a problem, but they certainly do enjoy it. They talk to me about it often, and I don't know if it's something I should discourage.

I was wondering what you guys thought about this, and why. The verdict is still out for me, and I just wanted to get some other opinions. Let me know.......................................peas
