What is truly worth savoring, something that only humans (and not just so-called higher animals) can appreciate, is not about indulgence, hedonism, or even drug use.
Rather, it is beauty, including the beauty of emotions. (This refers to emotions in moderation.)
In fact, so-called pure beauty, devoid of any emotion, does not truly exist.
To perceive beauty is, in itself, an emotion.
Only true human beings (adults, not children or high-level animals with child-like traits) can understand what I am saying.
Some people, and perhaps even many people, may never truly become adults, even as they grow old. (I cannot quantify this; it is hard to say exactly how many. From the prevailing social climate, whether in the East or the West, very few people are truly "grown-up." The entire world, in a way, could be seen as a giant nation of overgrown children. No one is truly better off than anyone else—it's just a matter of degrees, like the pot calling the kettle black.)
