045 - Fitness Trackers and Baby Powder

Don’t mind Chris’ newfound psychic powers: do fitness trackers like Fitbits actually work? They monitor our heart beats, they count our steps and calories burnt, but do they do it accurately? And can they help us lose weight? Also: you’ll never believe what actually motivates people to exercise; early detection is not as easy as it sounds; does Johnson & Johnson’s baby powder cause cancer and should you even use baby powder in the first place; and how to judge the merits of a scientific paper when you’re not a scientist.   Vox pop by Ada McVean of the McGill Office for Science and Society.   Jingle by Jillian Kate.   Additional music by Seth Donnelly and Kevin MacLeod.   Theme music: \"Troll of the Mountain Swing\" by the Underscore Orkestra.   To contribute to The Body of Evidence, go to our Patreon page at: http://www.patreon.com/thebodyofevidence/.   Patrons get a bonus show on Patreon called “Digressions”!
