Look into white albacore tuna. It has a much more mild smell and flavor than the less expensive light tuna. Since trying it 12 years ago, I can't go back to the stinky stuff. It is in the grocery store right along with the other stuff and even made by the same brands, just a little more expensive.
The few times I have gone any time away from analogs, it seemed to me that nonsmokers had much worse breath than smokers. With the smokers, it was just the ashtray smell, only less strong. The nonsmokers' breath smelled like rotten cadavers to me, literally. I still hung out with the smokers, at least they knew they stunk and made an effort not to waft it my way. The nonsmokers had no clue.
