Down the hatch
Aah, HERE it is! If I had to nominate the one thing that makes life in this form special it's the discoveries that turn our whole group thinking on its head.

We've already seen how society's views have adapted to the changing mortality rate. There is more interest vested in the current plain of existence with the advent of greater longevity and more fortuitous circumstances. Shorter lifespans would have required a shoring up of the afterlife as time and influence allowed little in this life.

But immortal? And imagine the profoundness of the tragedy when someone is killed where they could otherwise have lived on. Eternal life on Earth would not be blissful or heavenly; there would be many things to adjust to and problems to confront. I'm sure experientially it would be fantastic just to be able to create that Barbara Cartland concordance that you would otherwise not have had the time for. But it would affect the whole attrition rate and we've already seen the writing on the wall when it comes to population growth - what prospect for the future generations if their ancestors are still holding down jobs and influencing debate? How fast would our depletion of natural resources and food crops occur if we lived on indefinitely?
