Hmm, I'd say beer drinking definitely counts. I rarely drink beer alone, it's a social thing for me, so when I have a beer it's often when relaxing with mates, at a BBQ, over a meal with my wife or some such thing so I find it relaxing. So, yes I think it counts. Let's just throw it all in together, all beer-drinking and say, yep, good stress reliever.
Yeah, a couple of my handguns there...I'm more of a long range rifle shooter but I like to run and gun with handguns too.
