There are many days at work, where I lunch at my desk. I might have a small window of lunch time. Or I am trying to head home early. Or I just play feel like it.
A very long time ago, I discovered that a TED Talk fits nicely into my lunch slots – 18 min deadlines are useful! And the presenters & their ideas are not bad company at all.
I have added many of these lunch-time views into a YouTube playlist. If you are looking for good TED videos to watch, this collection could be your starting point.
