I love TED Talks. It always gives me something to think about, wonder, contemplate and ultimately incorporate into my being. This one is especially telling as our "social networks" have become increasingly virtual and not actual. Yet the ties, at least in my experience, are no less important, influential and necessary to the health and happiness of our being. Enjoy.
And thank you for being part of my network. I know I am better for it.
