Another great talk from TED:

Psychologist Dan Gilbert challenges the idea that we’ll be miserable if we don’t get what we want. Our “psychological immune system” lets us feel real, enduring happiness, he says, even when things don’t go as planned. He calls this kind of happiness “synthetic happiness,” and he says it’s “every bit as real and enduring as the kind of happiness you stumble upon when you get exactly what you were aiming for.”

Unfortunately, I cannot embed this presentation here, but you can find it at:

Alan Russell studies regenerative medicine — a breakthrough way of thinking about disease and injury by helping the body to rebuild itself. He shows how engineered tissue that “speaks the body’s language” has helped a man regrow his lost fingertip, how stem cells can rebuild damaged heart muscle, and how cell therapy can regenerate the skin of burned soldiers. This new, low-impact medicine comes just in time, Russell says — our aging population, with its steeply rising medical bills, will otherwise (and soon) cause a crisis in health care systems around the world. Some graphic medical imagery.
