I really enjoyed this episode (as I do all the episodes really).<p>The key information they presented was that just because bacteria evolve quickly to modern forms of antibiotics, doesn&#x27;t mean they don&#x27;t also reduce to their tolerance to older (in this case, 1000 years older) antibiotic-like medicines that we would dismiss outright because it wasn&#x27;t created in the modern age. Old medicine was very much trial and error, but it doesn&#x27;t mean it can&#x27;t also be effective or worth looking into deeper for ideas.
