If you ever feel alone, you shouldn’t, because you are actually surrounded by viruses. They’re in you, they’re on you and, in fact, there are more viruses in the world than there are stars in the sky. So why aren’t we sick all the time? In this episode Tai looks at how viruses work, how they travel, and the ways in which they shape our lives—both bad and good.
