What is Happiness?

After work today, we went to the Annual Baggs Memorial Lecture on Happiness, this year delivered by Matthew Parris. And I'm very proud to say that out of the four of us, I'm the only one who didn't nod off at one point or another.

Which then meant that I had to try and explain the nub of the argument afterwards.

Which was, in case you're interested, that there are basically two lines that make up ones life: things that happen to us, and how we feel about them. Happiness is when the two of them coincide, and then stored memories are put in the Strong Positive file in our brain. I think.
