They're easy to come by. Every day just check the news for any religious whack-job predicting the end of the earth, laugh, and then proceed as normal.
Is there enough days on the calendar for that?
Yup. Same thing with butterscotch flavor. Melted butter tastes good when cooked on vegetables, but when you smoke on something that tastes or smells like hot melted butter it's just nasty.
Talking of nasty flavours. I was given a tin of tobacco at Xmas, not much aroma came from the tin so I didn't know what to expect from it. On lighting it up the best description of it would be that it smelled and tasted like pencil shavings left over after sharpening a pencil.
I ended up mixing it with another tobacco just to use it up.
