Let’s speculate about immortality for a bit. It’s something that’s been on my mind a bit recently because… well, what with stem cell research and leaps in medical science, the problem of human mortality could reasonably be solved in our lifetime. I’m no doctor, and I haven’t done research on the actual progress being made, but frankly I’m far more fascinated by the potential long term ethical and social impact that this might cause. So let’s just lie back with something vision-inducing (I recommend running 20 miles) and try to glimpse the future.
