Hello Tangents listeners! We are off this week to rest up and enjoy the holidays, so in place of a regular episode we have a super special treat from friends of the show that we're excited to share! We're dropping an episode of a new podcast series from Chalk and Blade Productions called "Our Big Shot."What if we could build a disease free world? Well, we almost have. We are at a point in history where we have a Big Shot to make that happen. Dr Seema Yasmin, expert in disease control, brings you the stories of disease eradication, and the pioneers who can tell us how to finish the journey. These conversations will make you smarter, entertain and surprise you, and give you hope for the future of humanity.SciShow Tangents is on YouTube!
