A Classic Must See TED Talk

I was chatting with someone about body posture today and Amy Cuddy's amazing TED talk came up again, it seems to always come up!  If you have not seen this it is a must, it encapsulates so much that is essential in our time; about TED, about science, research, education and the power of belief in changing and improving yourself, and about the importance of sharing what it is you find with others.
