Dan Owens has been my editor since day 1 on this channel, either directly cutting or overseeing the editing on nearly 400 videos. Now that we've amassed 1 billion views on the channel, I thought it'd be fun to see what medical info Dan has retained over the years. He has to have learned something about health at this point, right? I quizzed Dan on how often you should change your underwear, what HIPAA stands for, collapsed lungs, muscular structures, cracking your neck, alkaline water, hiccups, the weight fat vs. muscle, arteries, tendons and ligaments, abs, sneezing, enlarge tongues, prenatal vitamins, and of course CHEST COMPRESSIONS.
