And if ‘I’ was to get ‘my’ way and things were of a lasting importance, that is not a good outcome at all, life would be a serious business. And if ‘I’ was to live eternally, what about those other human beings that are yet to be born, they would never get to experience the joy of being alive. How weird that the thing which is felt/believed to be at core what is ‘wrong’ with the universe - mortality - is what in the grand scheme of things ensures a happiness and harmlessness for all.
In this scenario of immortality life would be merely about surviving, enduring - of course that is a serious business. In actuality life is about enjoyment and appreciation, that is the reason this body is here.
