Well, I think I'm going to add to that broken record.
I don't smoke, and I never intend to. I have quite the passionate dislike of smoking.
I haven't done drugs, and I probably never will. I don't have a desire to.
I'll drink once in a great while, and it's only one or two drinks. Alcoholism runs in my blood, and it's a family habit I intend to stop.
Haven't really gambled. If a couple of my friends wanted to start a poker night or something, I'd probably join in, but I wouldn't blow my life savings at a casino.
And yes, I'm quite the gamer. I'm fairly sure I have an addictive personality, but I tend to avoid things that mess with my mind and my health. And with the other, my responsibility tends to keep me in check. But I'm not really the type to go out and go wild, anyways.
