If you listen to podcasts, check out the Stuff You Should Know podcast. (If you don’t listen to podcasts, this is a great one to start with). The hosts, Chuck and Josh, take hour-long deep dives into literally hundreds of different topics. Here are some of their recent subjects: caffeine, Isaac Newton, Satanic Panic of the 1980s, the Great Wall of China and maggots. Each episode is full of great facts and plenty of comedic relief.
They have built up 500+ episodes of the podcast so you can listen for a LONG time before you run out of fresh content. Plus they are still publishing two podcasts per week.
