In History Vs., a new podcast from Mental Floss and iHeartRadio, we’ll explore how larger-than-life historical figures faced off against their greatest foes. In this inaugural season, we’re looking at Theodore Roosevelt’s incredible life using a convention that he, as a boxer, would have appreciated. Each episode, we’ll analyze how Roosevelt took on a particular challenge, from his debilitating childhood asthma and conflict within his family to conquering the hours of the day and preserving the world for the next generation.
