Aside from all the health issues that smoking is alleged to cause (no, I'm not saying it doesn't cause cancer, but let's face it - what doesn't cause cancer these days?) what about this for a reason..
It stinks!!!
Like, really bad...
When I was smoking, I had no idea just how bad the smell was...
The smell of freshly lit cigarette is, for an ex-smoker like me, occasionally appealing, but the smell of stale cigarette smoke on anyone is just foul...
Plus, you're gonna be eating MUCH less food...
So I'm guessing you actually want to TASTE the food you'll be eating...
Of course, that's all just my opinion...
