Happiness as a habit!

I have pretty regularly posted videos from TED as it has so much amazing stuff on it and here is another for you.
I am not huge on the importance of the notion of happiness as for me a sense of contentedness (is that a word?) is probably more attainable and reasonable to strive for.
However, even though I don't believe that Tibetan Buddhism has all the answers, the speaker in this video has explored the notion of happiness from a scientific point of view also and it is an interesting take on it.
So enjoy the monk, Mattheiu Ricard, on the "Habits of Happiness".
