I have some that I've assigned a mental hold date of "do not open before ....." to. But that's just because I think they'll improve with a little age, and it gives me something to look forward to in the years ahead.
Other than that, I'm liable to light up anything I have at pretty much any time. When I finish the last one from a box or cab, I feel good - not sad.
I don't have quite as much time left on my warranty as a lot of you. Like Dave said, I don't want my last thought to be "Oh Hell, I never smoked that .....".
