Recently I was exploring the TED website (TED.com) looking for information on the brain.

(I’ve written before about TED.)

One item I found was a presentation by Dan Gilbert, author of Stumbling on Happiness.

Dan explains in his presentation a bit about how our brain simulates situations without having to actually experience them (e.g., would you want liver and onions ice cream?), how we artificially create happiness, how we change our mind about what will make us happy and how we can be very wrong about what will make us happy.

I think it is worth the time (21:28) to view it.
