Interesting Jos ... thanks for posting the link! I even recognize a few names and there are definitely some interesting topics. I might even spend some of my Sunday getting educated. <g>
I sent the link to my youngest son (he's 23), who is always watching videos on TED (www.ted.com). Any TED video link he's ever sent to me has been quite interesting and I now see that some of the links on your link are from the TED site.
