I discovered TED a while back and have decided that some of these great talks need to be shared with the diving community. After all, their tagline is "Ideas worth spreading". Some of them are a bit long, but very worth watching and listening to. Some are way above my head, but I learn something from every one I watch. Most will not be about "SCUBA diving" per se, but will deal with issues very closely related to our great lifestyles. Anyway- I find them very interesting, hopefully some of you will also!
