You might know John Green as the author of bestsellers such as The Fault in Our Stars and Looking for Alaska, or from the hugely popular Crash Course and Vlogbrothers Youtube channels. John’s latest obsession is tuberculosis, the deadliest disease in the world — and he writes all about it in his book, Everything is Tuberculosis. John and Mattea Roach dive into the wild history of the disease, why it persists today and John’s personal relationship with a young tuberculosis patient from Sierra Leone.
