I warned you about this last week, but I couldn't resist recommending another podcast.
Gimlet Media recently launched a new show called Suprisingly Awesome. The show is hosted by Adam Davidson, of NPR's Planet Money, and Adam McKay who is well known for writing and directing Anchorman and Step Brothers.
Here's their description of the show:
Surprisingly Awesome is a show full of stories like this. Stories about things that sound totally boring, but turn out to be totally awesome.
Episode 3's topic is: Concrete. Naturally concrete doesn't seem to be a very exciting topic but I think you will enjoy the episode.
