On this episode of the Most Useful Podcast Ever, Jacqueline Detwiler tries biohacking to (hopefully!) become smarter, healthier, happier, more creative and more productive. Experimenting with specialized diets, float tanks, and microbiome testing, we try to find out what works and what doesn’t. Dr. Molly Maloof calls in to explain the science behind biohacking as a legitimate way to improve our bodies, and tech editor Alex George explains how to train your mind to go back to school. Lastly, we try CBD oil, a chemical in marijuana, to see if we can actually feel it working.
