The Supermoment is an especially beautiful situation in your lifetime where smoking didn't play a major role yet and the remembrance of this moment is very strong.
For example, my Supermoment:
In early May of 1978. I'm 14 years old and since my 9th birthday I have done Jiu Jitsu. After a training session, I am waiting for a tram at the stop. The sun is low and the air is cool but it feels nice. In my mind I recall two fights, which I have won that day. Slowly I'm falling into a hypnotic state. My body feels exhausted and strong at the same time. The world around me is shining with stunning brilliance and my body is filled with deep happiness
