Flow, The Secret to Happiness?

"So my research has been focused more on -- after finding out these things that actually corresponded to my own experience, I tried to understand: where -- in everyday life, in our normal experience -- do we feel really happy?

So existence is temporarily suspended. And he says that his hand seems to be moving by itself.
