FROM THIS EPISODE

How much can you jam into a human brain? How far can you push yourself past feelings of exhaustion? We examine human limits. We talk to Ironman tri-athletes and hear the memorable tale of a man who couldn’t forget. Are we limited by the size of our brain and the strength of our muscles, or will there always be a way to push ourselves just a little bit further? And what about human comprehension? As science barrels forward, will we reach the limit of human understanding?
