Starkist doesn't want tuna with good taste. Starkist wants tuna that tastes good.
A factor that no one has commented on is that, as we become older, our ability to smell and taste diminishes. In addition, medications such as beta blockers and our use of tobacco can further impair our taste receptors. That bourbon tasted better back in the day is not just a matter of nostalgia, it is a matter of physiology. Perhaps bourbon tasted better back then because we had better tasting apparatus back then. Of course, it is still possible that bourbon really did taste better back then.
I'd rather have a bottle in front of me than a frontal lobotomy.
I'll take my nostalgia over ice, if you please.
