Last night I had the for­tune to watch I Am Legend star­ing Will Smith. The premise of the movie is that Robert Neville (Will Smith) is the last man alive, after a deadly super-​virus lays waste to 90% of the worlds pop­u­la­tion. 1% of man kind had a nat­ural immu­nity to it, and 9%… well that’s some­thing else.
