Human life expectancy is getting longer. In 1910, humans in the United States were only expected to live 40 to 50 years. Now, in just over a century, we've nearly doubled that, with an average lifespan of almost 80. According to futurist Jamie Metzl, we're working on technology to extend that even further. "What If" is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. Join us on an imaginary adventure through time, space, and chance while we boil down complex subjects in a fun and entertaining way. Produced with love by Underknown in Toronto.
